AS institutes(summer classes) in Islamabad?

[Abdulah Mudassir]

I am about to go to Pakistan for my vacation but my october/november AS exams will be coming soon. Are there any good schools or institutes that provide summer classes or something similar? I need to study there for like 2 and a half months. I live in Rawalpindi but going to Islamabad is also acceptable. On a side note my friend's sister also wants to study for her AS. Can someone please tell me some of the more influential or lets say better at teaching places? Thanks in advance.
