AK Lectures MCAT Review

AK Lectures is worth your time if a specific science concept has stopped making sense and you want it explained properly, for free. It is not worth building a study plan around, because the free library is six science subjects and two of the four MCAT sections get nothing from it.

The channel is run by Andrey K under the handle @AKLECTURES, and it has 855,000 subscribers and about 2,000 videos as of September 2026. The same library is browsable on aklectures.com, which describes itself as "A Library of Over 2,000 Free Lectures" across biology, general chemistry, organic chemistry, biochemistry, classical physics and modern physics.

AK Lectures Overview

AK Lectures is a one-person science lecture library. Andrey K records whiteboard-style explanations of single concepts, usually 5 to 15 minutes each, and files them by subject rather than by exam. There is no MCAT course, no syllabus and no schedule. You arrive with a topic and leave with an explanation.

That design is the reason the channel keeps getting recommended for the MCAT even though it was never built for it. Most free MCAT video content is pitched at exam level, which means it tells you the rule. AK Lectures tells you where the rule comes from. For the amino acid chapters, the glycolysis and citric acid cycle steps, the enzyme kinetics plots and the electrochemistry that students most often lose points on, that extra layer is the difference between recognising a term and being able to reason through a passage.

What the free library contains:

• Biology, including cell biology, genetics and physiology
• General chemistry
• Organic chemistry, including mechanisms drawn step by step
• Biochemistry, the strongest part of the library
• Classical physics
• Modern physics

What it does not contain, anywhere in the free library: psychology, sociology, critical reading practice, practice questions, full length exams, score reports and progress tracking. Nothing on the site or the channel asks you to create an account to watch, and there is no guarantee attached to anything because nothing free is being sold.

There is a second, separate product. The medical lecture packages are a paid subscription to 1,100 plus videos in 15 medical school subjects, including pathology, pharmacology, microbiology and behavioral science. Those are aimed at medical students and board exams, not at premeds.

AK Lectures MCAT Review For 2026

The free library misses one whole MCAT section

This is the finding that matters most and the one nobody states plainly. The AAMC sets the discipline targets for the Psychological, Social, and Biological Foundations of Behavior section at 65 percent introductory psychology, 30 percent introductory sociology and 5 percent introductory biology, across 59 questions in 95 minutes. The AAMC notes those targets are approximated to the nearest 5 percent and vary between test forms.

Psychology and sociology together are 95 percent of that section, roughly 56 of its 59 questions. The free AK Lectures library has no psychology subject and no sociology subject. The only behavioral science AK Lectures offers sits inside the paid medical packages, and it is written for medical students, not for the MCAT content outline.

AAMC discipline targets for Psych/Soc against the free AK Lectures subject list, both read September 2026.

CARS is the second gap, and a simpler one. There is no reading comprehension content at all. If you want structured CARS work you need something built for it, such as Jack Westin CARS practice.

So the honest scope of the free library is the science content of two sections, plus the 5 percent biology slice of a third. Any study plan that treats AK Lectures as your video resource is quietly skipping a quarter of the exam.

Depth is the strength, and also the cost

Where AK Lectures does cover a topic, it usually covers it further than the MCAT requires. A single glycolysis lecture will take you through the enzyme names, the regulation and the energetics. That is genuinely useful when a concept has not clicked, and it is why the biochemistry section of the library gets recommended more than any other.

The cost is time. Fifteen minutes on a mechanism you needed two minutes of is fifteen minutes you did not spend on practice. Watching lectures also feels productive in a way that answering questions does not, which is the classic trap of free video content. The MCAT rewards application, and this library contains no application.

The practical rule: come with a named gap, watch the one lecture that fills it, leave. Do not work through a subject front to back. If you want a schedule that puts video review in its place next to practice, our MCAT study schedule guide sets out the ratio.

Production, age and the platform

The videos are plain. A whiteboard, a marker, a clear voice, no animation and no production polish. Most students find the pacing slow and watch at 1.25 or 1.5 speed. The audio is consistent and the diagrams are legible, which is more than can be said for a lot of free science video.

The library is also old. The most viewed lecture featured on the channel home page, on the urea cycle, has 549,288 views and was posted 10 years ago. For biochemistry and physics that matters very little, because the science has not moved. It does matter for anything tied to the exam itself, because nothing here has been revised against the current AAMC content outline. Use it for concepts, never for exam format or strategy.

Two platforms hold the same material. The YouTube channel is easier to search and gives you speed controls and captions. The website organises the same lectures by subject and topic, which is better when you want to see what a chapter contains rather than hunt for one video.

Pricing

The science library is free, with no account and no trial period. That is the product almost every MCAT student means when they mention AK Lectures, and the price is the strongest thing about it.

The paid product is separate and is aimed at medical students. The medical lecture packages cost:

All three give the same access to 1,100 plus medical lectures. Prices were read on the AK Lectures pricing page on September 21, 2026.

For an MCAT student, the answer on the paid tier is no. It covers pathology, pharmacology and clinical subjects that the MCAT does not test, and the behavioral science inside it is pitched at medical school, not at the AAMC Psych/Soc outline. If you are choosing where 20 dollars a month should go during MCAT prep, a question bank earns it and this does not.

Who AK Lectures Is Best For

AK Lectures is a good fit if you are a self-studier who is already doing practice questions and keeps hitting the same concept walls. It suits people who want the mechanism rather than the mnemonic, and it is particularly good for biochemistry and organic chemistry, where seeing a process drawn out beats reading it.

It is also a sensible free companion to a paid course. Students using a structured programme such as MCAT Self Prep, which already points its lessons at outside video including this channel, get the concept depth without paying twice.

It is a poor fit if you want structure, if you need psychology and sociology, if you learn by doing rather than watching, or if you are short on time. Six weeks out from test day, this library will cost you more hours than it saves.

When You Might Look Elsewhere

Khan Academy MCAT is the obvious free alternative, and for Psych/Soc it is the better one, because its MCAT collection does cover psychology and sociology. Our Khan Academy MCAT review goes through what survives of that collection and what does not.

If the real gap is practice rather than explanation, video is the wrong purchase. A question bank such as UWorld MCAT puts you in passages with explanations attached, which is the work the exam actually measures.

If you are trying to lock in facts rather than understand them, spaced repetition beats lectures. The AnKing MCAT decks do that job. You can compare the rest of the free video options on our list of MCAT YouTube channels, and the way we score every resource is set out in our review methodology.

Final Verdict

AK Lectures earns 3.9 out of 5 as a free MCAT resource. The score is held up by the quality and depth of the science explanations and by the fact that it costs nothing, and held down by scope: no psychology, no sociology, no CARS, no practice.

AK Lectures FAQs

Is AK Lectures free for MCAT prep?

Yes. The science library of more than 2,000 lectures is free on YouTube and on aklectures.com, with no account required to watch. AK Lectures also sells a separate subscription to 1,100 plus medical school lectures, starting at $19.99 a month on the six month plan, but that product is aimed at medical students and is not MCAT material.

Does AK Lectures cover MCAT Psych/Soc?

No. The free library is six science subjects and contains no psychology and no sociology. The AAMC sets those two disciplines at 95 percent of the Psych/Soc section, so you need another resource for roughly 56 of its 59 questions. AK Lectures does have behavioral science videos, but they sit inside the paid medical packages and are written for medical school.

Is AK Lectures better than Khan Academy for the MCAT?

They do different jobs. AK Lectures goes deeper on individual science concepts, especially biochemistry and organic chemistry. Khan Academy covers more of the exam, including the psychology and sociology that AK Lectures leaves out. Most students who use both use Khan Academy for coverage and AK Lectures when a specific concept will not click.

How old are the AK Lectures videos?

Much of the library is close to a decade old. The most viewed lecture featured on the channel home page was posted 10 years ago and has more than 549,000 views. That is fine for biochemistry and physics, where the underlying science has not changed, but it means nothing in the library reflects the current MCAT format, timing or strategy.

Does AK Lectures have practice questions?

No. There are no practice questions, no full length exams, no quizzes and no progress tracking anywhere in the free library or the paid packages. Everything is video explanation, so you need a separate source of practice material.
