Scared!!

My viva (oral exam) for Pharmacology is scheduled for Friday. The external examiner will most probably be Brigadier Najmi of Army Medical College (I think) and the internal examiner is o Head of Department and former Principal of our college, Rawalpindi Medical College, Dr.Shahnaz Aftab. Both are notorious for failing students and have built up a reputation for scaring the shit out of us students. And like other medical students, I too am literally peeing in my pants (sorry for the relatively foul language....But this will emphasize my feelings more accurately). Dr.Shahnaz Aftab during her tenure as Princpal stripped our Class Representative and Girl Representative of their offices because they asked permission for a class function. She said that she thought this was a "bahana" for taking girls out on a date. Anyways, this is a long story and I"ll get to it on some other post. She also wants all the boys to dress up in ties, comb their hair nicely, brush their teeth, shave their beards, and polish their shoes before entering her office. She said boys smell so bad that she has to turn her face to the other side before proceeding with the viva.
And if I wasn't scared enough, I just learnt yesterday that the external of Pathology will be General Hannan. And the Head of Department himself is scared of what might transpire. He is running around telling us students to prepare Microbiology very well. General Hannan is a very experienced and reputed teacher of Microbiology and also taught our Head Of Department Dr.Abbas Hayat.
So I have some real studying to do, and I don't know where to start where to end. This is going to be one tough month :(. I hope Allah Helps me get through this in once piece. Ameen.
