Can I throw this out there and say that I don't think Flash Cards are a good study resource for this exam at all.
*UNLESS you are still learning the concept and except maybe for Orgo...maybe
Otherwise, a flash card can fool you into feeling like you know something when all you really know is how to spit out a definition or regurgitated answer.
This is not what you want for the MCAT - you need to be able to understand the concept and reason/critically think about it and flash cards will not help you with this.
Just my 2 cents...
