Choose Your MCAT Starting Point
You don't need every MCAT resource on the internet. You need the right support for where you are today. Choose the starting point that fits your needs.
I'm Retaking the MCAT
You have a score and a study history. Find the content, timing, or reasoning gaps that need to change before another attempt.

Explore Complete MCAT Prep →CARS Is Hard. Understanding Why Is the First Step to Improving.
Testing Solutions began with a focus on critical reading and reasoning. Dr. Nick developed an approach to CARS that grew into a book, a training program, and eventually a complete MCAT preparation course. That same emphasis on understanding passages, evaluating evidence, and thinking critically continues to shape how we teach today.
If your science sections are fine and CARS keeps dragging your total down, another pass through content review won't move the number. What moves it is having a process you can run on a passage you've never seen, on a bad day, with the clock running.
Why Is MCAT CARS So Hard?
One Goal. Different Ways to Get There.
Focus on CARS if reading and reasoning are holding you back. Choose complete MCAT prep if you need structure across the exam. Or start with your AAMC practice results to identify what needs attention first.

A Retake Isn't a Do-Over. It's a Rewrite.
Your last score is data. Before you run the same study plan again and hope for a different number, find out what actually cost you the points. Content gaps, passage analysis, timing, and where your study hours went are all measurable.

Not Ready to Start? Start With One Question.
You don't have to figure out your entire MCAT study plan today. Start with one practice question a day to become more familiar with the exam, practice your reasoning, and build a manageable study habit.
It's a simple way to stay engaged with MCAT preparation, whether you're just getting started or studying between classes.

Testing Solutions began in 2015 when Dr. Nick Zehner developed a structured approach to reading and reasoning for the MCAT. After scoring in the 99th percentile and graduating from Stanford University School of Medicine, he continued building educational resources to help students understand passages, evaluate arguments, and approach questions with greater confidence. His focus remains on teaching practical reasoning skills that students can develop through consistent practice.
