MBBS 1ST YEAR PHYSIOLOGY (Important)

By Farkhanda Qaiser

As the HOD of physiology has changed this year so there maybe slight modifications in the important topics this year. I guess Maam Mehr un Nisa must have stressed upon the topics that are really important so my advice is do not ignore the guess that has been given by her…!!!

And the rest of the tidbits are the same as I’ve given earlier.

This was the question paper of the profs 2010 and I have questions of class tests too but I don’t think they’d be of any use now. You (I’m assuming if someone does read this, it would be only 1^st year) should look up your own class tests of this year and high chances are that the prof questions would be mostly from among those. But yeah the purpose of telling important topics is that you should prepare these better than the rest. At no cost, it means that you should do ONLY these topics. No, no, that would be disastrous for sure. So do everything and have faith in Allah. Good luck =)
