See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

You: A buffer has a conjugate base to acid ratio of 10:1. If the pKa is 4.8, what is the pH?
Kuest: Which equation links pH, pKa and the ratio of base to acid?
You: Henderson-Hasselbalch: pH = pKa + log([A-]/[HA]).
Kuest: Right. So what is log of 10, and what does that do to the pH?
You: log 10 is 1, so pH = 4.8 + 1 = 5.8.
Kuest: Exactly. Every tenfold change in the ratio moves the pH by one unit, which lets you answer these without a calculator.

In a buffer, a 10:1 base-to-acid ratio puts the pH one unit above the pKa.

The method

How to study MCAT with Kuest

The MCAT rewards applying science to unfamiliar passages, not reciting facts. Strong prep mixes content review with spaced recall of high-yield facts and lots of timed, passage-based practice followed by careful review.

  1. Set a plan to your test dateStudy plan

    Tell Kuest your test date and weekly hours and get a schedule that balances content review, practice passages and full-length tests.

  2. Learn the concepts behind each passageTutor chat

    Ask about any topic, from enzyme kinetics to social stratification, and the tutor explains it step by step and checks that you follow.

  3. See pathways and mechanismsTeaching board

    Use the teaching board to draw metabolic pathways, reaction mechanisms and physiology diagrams you can walk through piece by piece.

  4. Keep high-yield facts freshFlashcards

    Turn amino acids, hormones and psych terms into flashcards with spaced review so they stick until test day.

  5. Practice passages under timeMock exams

    Take timed mock sections built around the topics you're studying and get an explanation for every answer.

  6. Find your weak areasGap finder

    The gap finder groups your misses by topic and skill so your next week goes to what actually costs you points.
