I used it pretty extensively. It took me a little bit of time, but I edited out all of the jokes and this helped immensely. They're sort of funny the first time through but are incredibly tedious when you're listening for the 10th time. I did the following:
- Read the corresponding content in the EK book
- Listen to audio one time through sitting down with book in hand
- Deep read the corresponding content in the EK book (highlighting and doing the problems)
- Then I'd listen to the audio one or two times through
- Re-listen to the audio every so often (I would throw it into a "listening while doing stuff" rotation of other lectures I had completed).
- Re-listen/review when I missed a particular topic e.g. Oh I messed up the Kreb's Cycle, better go back and review/re-listen
There is no way this would get you all the way to preparation like they claim, but I found it useful to consume this content in a different form. Taken alongside books, flashcards, practice tests, and videos, it is a nice addition and pretty easy for most people to fit into their schedule.
Note that this was set up for the old-MCAT and thus not everything will be covered and some of what is covered won't be on the MCAT. Take a particular look at their physics lectures and later orgo lectures because there will be ones you can skip entirely. I'm sure you can find it if you just do a search.
