Warning about Apollo step 1 audio products!!
Please dont use these APOLLO usmle audio gold package even if you get it for free somehow. The reason I say this is because these audio lectures are full of errors.
I even thought about making an errata for them but it would have taken too much time up, thats how many mistakes there are.
It can be a detriment to your studies considering they mix up things that are already confusing for example Lysosomal storage disease. (thats only 1 example of the type of errors they have)
Final note: aside from the many many errors, much of the material they cover is not considered high yield.
I hope I spared people a waste of time and money and most importantly, a wrong answer on the test.
