    biology TEACHER (Lahore)

    Not sure why some ppl are recommending Miss Nighat Gul, I used to sleep in her class & thank God my section was changed then. :P The best teachers for bio in Lahore are Miss Saira & Sir.Zafar Sulehri. I've taken tuition from Zafar Sulehri at GHA Gulberg for a short time, he is a great teacher.

    How was your biology paper 22? I am so sad and devastated.

    Paper was quite easy & there was plenty of time. However few of the parts did pose some challenge. Overall I am expecting good marks in this paper as well as p5, gt could be around 44-48.
