Asalamu alikum wr wb!
Dear Juniors,
This thread is intended for your help. I found the community here very helpful which has inspired me to do the same for others. Now I've collected SOME questions of MCAT 2012 (some from my memory, and some from other sources which i'll share with you at the end).
Please remember that some questions might be incomplete or inaccurate, but I've tried my best to find the accurate ones and have checked them against my memory too. So you can pretty much comfortably rely on these. Maybe the other members can confirm them too who gave entrance test in 2012?
...just continuing the legacy of "sharing knowledge".
Plx remember, do not hold back knowledge. The more you'll share it with others, the more it'll grow. So keep sharing...
