A Method, Not Tricks: In the Families’ Own Words

All reviews on this page are reproduced just as parents and students wrote them.

The reviews below span more than a decade of practice. Most can be verified on Wyzant, where Dave got his start, teaching under his legal name, David. Nothing is rewritten; where a family reported scores, they appear beside the reviewer’s name as well as in the review itself.

SAT Reading & Writing

“I highly recommend David W. as an SAT tutor. With his help, My child was able to improve the score by 80 points. He’s patient, knowledgeable, and explains concepts clearly, making even the toughest sections manageable. His strategies and practice materials were targeted and effective. If you’re looking for a proven tutor who delivers real results, David W. is an excellent choice.”

“I very highly recommend Dave for SAT Reading preparations. Dave has an absolute knack to help quickly understand the core logic and reasoning behind the various answer choices and how to approach solving the most difficult and confusing questions. He makes it so easy to logically find the precise answer choice without any guesswork or confusion. His process and methodology of coaching is thorough, organized and highly engaging. His coaching and guidance has been incredible and paramount for significantly raising our child’s SAT Reading score in a very short period of time. Our child had initially self prepared and received a score of 670. We then started classes with Dave and within 2 months, the score increased to a 720 and then another month later to a 740 for a 70 point score improvement.”

“Within my own experience of learning, taking, and hearing advice from COUNTLESS tutors regarding the SAT, there is no one I know who can match the expertise and objectivity that David brings to analytically solving the SAT English Section. When you take classes with David, it’s not a matter of luck or mindless practice that will achieve outstanding scores—it’s his focus on removing all subjectivity associated with SAT English and treating it as a factual science. There is an undoubtedly clear explanation for every right answer and a blatantly obvious reason for every wrong answer. David achieves this approach by breaking down the English portion into various sections with an exact way to solve each answer. He will provide the resources and tools to understand the method and solve seemingly ‘subjective’ questions analytically. In my scenario, I was looking for a tutor who could help me reach close to perfection in the English Section, and David did exactly that. I went from scoring 730 to 770 in the English Section, bringing my SAT to a 1570. Whether you are looking for major improvements or slight refining, David is the go-to guy and will provide intuitive analysis skills that will persist beyond standardized tests.”

“Last summer, my son studied for the SAT on his own, but there were some difficult questions he simply couldn’t conquer, no matter how hard he tried. I realized he needed professional help, so I read many SAT tutor reviews and found David. Unfortunately, by then it was too late to book him because his schedule was already completely full. So, I planned ahead for this summer and contacted David more than six months in advance to reserve his time. It turned out to be a great decision. My son has benefited tremendously from David’s tutoring this summer, and his practice scores have improved to the 760–770 range. He will be taking the SAT on August 22. David is truly a master in this area. The investment is absolutely worth it—you will not regret it.”

“I am absolutely thrilled with the incredible progress that I made in the SAT Reading & Writing section, thanks to Dave Walker’s exceptional tutoring. Starting with a score of 630 and through Dave’s tutoring, achieving an impressive 710, the results speak volumes about Dave’s expertise and dedication. Dave is an extraordinarily thorough and hardworking tutor who truly cares about his students’ success. His personalized approach and complete understanding of the SAT content made all the difference. He consistently provided clear explanations, practical strategies, and encouraged support throughout the preparation process. After every session, Dave provides an in-depth, written run down of the details of your session, emphasizing which skills need the most improvement. Dave assigns work that is individually targeted toward the skills you need the most focus on. The remarkable improvement in my score is a testament to Dave’s effective teaching methods. I am extremely grateful for his guidance during this pivotal moment in my academic journey. I highly recommend Dave to any parent seeking a qualified and committed test prep tutor.”

“David is an awesome tutor, and we are very happy to find him as a mentor for my daughter. He tutored her for SAT EBRW, the score improvement is beyond our expectations from 670–750. We had a preliminary meeting with Dave to discuss expectations and where help is needed prior to the sessions, he has reviewed my daughter’s previous SAT scores, discussed the troubles she is having, and reviewed in depth the official SAT and PSAT scores to understand her weaknesses. We had 4 tutoring sessions just 10 days before the SAT and his lessons were so focused and personalized. The techniques he taught her has helped her alot. He provides detailed feedback after each session and assigns homework that is very well documented. We have tried several other tutors but David is unique and highly recommends his services.”

“My son took 3 week crash course with Mr. Walker and he was amazing. Within 3 weeks prep he got 80 point jump from 670 to [750]. We highly recommend Mr. Walker for SAT Language Prep.”

“David W. is an exceptional tutor, and I’m delighted to have discovered the ideal mentor for my son, whose SAT scores saw significant improvement under David’s guidance. Thanks to David’s support, my son boosted his reading and writing scores from 650 to 720. David displayed remarkable insight into my son’s needs and adeptly steered him toward achieving his goals. His tutoring techniques were lucid and easy to follow, and he maintained remarkable patience throughout the process. With David’s assistance, my son secured admission to a top university. Impressed by his work, I’ve also enlisted David’s help in enrolling my daughter in his upcoming summer classes.”

“My daughter was waiting until last min to prepare August SAT this summer. She said she could study alone, but I did know she needed very specific guidance to get higher score. She got 700 from 1st SAT reading & writing and language sections. I worried she could get lower score. She needed at least 30 point more before school started. Time was running out. I knew teaching reading comprehension is very difficult task, raising score in 700 range was a challenge. I was going through this website, and I accidentally found David W., but read all his reviews. I found consistently Scores were improved. That convinced me David could find each students’ learning style, weakness, and strategy to improve scores. That worked. One of the best decision I made against my daughter’s choice. From the first tutoring session, David found weakness, identified areas to improve scores, and guided my daughter. He found repeated weakness, and focused on same area, not to make same mistakes. During 3 weeks, my daughter had 6 sessions in total, her score has improved 50 points, she got 750. That helped her to meet her goal. I like the idea of ‘sharing Google Doc’, he could see my daughter’s note taking during session, that made her more concentrated, sharing same notes helped my daughter and David for consistency in learning. That prevented ‘jumping from one area to another’ from one session to another, that was quite common through on-line tutoring. Time-wise, and investment-wise, that was the right decision. We could move on next step for college preparation.”

“My son had the privilege of working with David, a truly exceptional SAT tutor. His professionalism and consistent preparation were evident in every session. David possesses a unique teaching method that not only explains theory, but ensures a deep understanding of question types. He also teaches how to promptly identify incorrect answers. My son, a highly motivated student, truly enjoyed working with David and learned analytical skills that apply in any academic setting beyond just the SAT. In summary, David taught my son a methodical approach to the test which significantly boosted my son’s score. The results speak for themselves — my son’s English score went from a 700 to 770, and I know that improving at this higher tier is not easy. So, for students seeking genuine SAT comprehension, I wholeheartedly recommend David’s services. Don’t hesitate; he is the key to unlocking true understanding of SAT questions.”

“David is a patient and responsible tutor. He taught my daughter well after the 1st SAT. Her second SAT writing score improved significantly from top 42% to top 17%. Many good suggestions we received from David. Thank you.”

“I worked with David for several months on the SAT English and Writing and Language sections. He was the exact tutor I was looking for when I was first starting my prep. He has created a method of approaching this part of the SAT that improved my score tremendously. He is the perfect tutor if you want someone who will show you and walk you through the exact steps you need to take to tackle all the questions on SAT Verbal. I am not and have never been a strong English person, yet through his help, I went from a 600 to a 740 (and was scoring 760s on practices). I went from getting 17 wrong on the reading comprehension to only 3 on real exam. He only uses the real tests, so all of his help was the exact material.”

“I’m a rising junior in high school, and I reached out to David December of 2020 in preparation for the June SAT. After taking classes with David once a week for around five months, my score went from 1300 (650 for reading and writing) to 1580 (780 for reading and writing). I loved his teaching methods and found that his test-taking tips were super helpful. David has a solid understanding of the structure of the test, and I really liked how he only gave me real tests as homework so I was fully prepared. I would not have been able to do as well as I did without his great tutoring!”

ACT English, Reading, and Science

The same method, applied to a different test.

For most of Walker Prep’s history, Dave taught ACT English, Reading, and Science alongside the SAT. The practice’s focus has since narrowed to SAT Reading & Writing; these reviews remain part of the record.

“David is an awesome tutor, who made a huge difference in my son’s ACT scores in just a month!! He worked with my son in SAT Reading and Science in particular, he also helped with English. My son’s ACT scores went up from a 33 Composite (36 English, 35 Math, 30 Reading, 31 Science) to a 36 Composite (36 English, 36 Reading, 35 Math, 35 Science) His Reading score went up from a 30 to a 36, while his Science score went up from a 31 to a 35. Not only did his score improve significantly but he also got a perfect overall score of 36! And all this in just one month of tutoring 2 times a week. We are supremely happy with his coaching skills and tips. I think I made the best decision in choosing David as my son’s ACT tutor. David is an incredible tutor and coach and I very strongly recommend him to anyone who’s looking to improve their ACT score.”

“Our daughter’s story started in December 2020 with an ACT Reading score of 23 (10 questions unanswered because of lack of time, plus some wrong), and an English score of 29 (English is our second language). Just 3 months later, working with Mr. David once a week the results were astonishing: English 35, Reading 34. All because of Mr. David’s detailed explanations and his unique approach. We cannot thank you enough Mr. David!”

“If you want your son or daughter to VASTLY improve their ACT scores, David is, without question, the tutor you need. With David’s amazing help, my 16 year old son went from a 31 in English to a 35! And from a 29 in Reading to a 34! David is a remarkable test prep tutor because he is clear, patient, organized, and EXCEPTIONALLY knowledgeable about the ACT and EXACTLY how it works. On the personal side, my son found David to be enthusiastic, supportive, and full of great tips to maximize his scores. Finally, David instills confidence in your child, perhaps the most key ingredient when preparing for the SAT or ACT. We are grateful and consider ourselves fortunate to have found him — DAVID gets our HIGHEST RECOMMENDATION.”

“David tutored my daughter for 8 sessions over the course of 1 month prior to her retaking the ACT. David did a great job assessing her strengths and opportunities and put together a strong plan to improve on her English section score. Her first ACT English score was 29 and after tutoring, she earned a 35 on the English section. David communicates clearly and helps kids learn what they need to know for the ACT. We highly recommend David — what more can we say — 6 point improvement! Thank you David!”

“David is an excellent tutor. He is always ready, patient, and gives great feedback. I specifically used David for ACT prep. After I took the ACT on my own. I completed 13 sessions with David and I had great increases in all subjects that he tutored me on.

“Here’s what I got for point increases:

“Composite: +4
“English: +4
“Reading: +4
“Science: +7

“With his help, I am able to apply to the Air Force ROTC with a great chance of getting a scholarship and I’m also eligible for the Bright Futures Scholarship in my state!

“Thanks for all your help and encouragement, David!”

“David is an OUTSTANDING tutor if you want serious prepping for the ACT. My son loved his methods of teaching from day one. Today we received my son’s September ACT test scores and I am extremely pleased. The first time my son took the ACT back in April (totally unprepared), his scores in English, Reading and Science were, 27, 29, and 27 respectively. After engaging with David over the summer (once or twice a week), my son took the test again. HIs scores were 35, 33, and 34 respectively. (I did not including the Math score because we had a different tutor for Math). In any case, a solid five point gain on his composite score is clearly significant — it places him in the top 1% bracket nationally. His composite score could have been higher if it weren’t for his lower score in Math, where he got a 28, but the high scores in the other sections helped bring his composite score up high. I HIGHLY RECOMMEND DAVID. Thank you, David. You are awesome.”
