alevels >> Islamic studies

Presumably you're referring to Cambridge International's A Level Islamic Studies (9488), here. Is that right?

Are you hoping to study this independently and then take the exams at a local exam centre as a private candidate?

You say, "if anybody can guide me on this ..?" What sort of guidance are you seeking? How to locate an exam centre which accepts private candidates? Guidance with the content of the course, and how to learn it? Something else? Or perhaps you're looking for a school/college which teaches this subject?

from Pakistan , currently in Alevels ...
I am thinking about taking Islamic studies as a subject and give the paper composite
if anybody can guide me on this ..?
and btw I couldnt find the textbook ...

If you are Muslim this seems strange. Wanting an A level on something you’ve been studying your whole life. It’s like taking a GCSE or A level in a native language to someone who has English as a second language. Some unis will likely see this the same, like trying to get an easy top grade to try and look better. It comes across as deceptive.

I think he needs all that but hasn't got any clue about what questions to ask

I disagree. There is nothing deceptive about wanting to take islamic studies as a muslim. Not all muslims have been "studying Islam their whole life", this is a generalisation of 2,000,000,000 people. Please provide evidence that "some unis will likely see this the same". And don't gatekeep muslims from learning about their own religion.

No studying an a level in something related to your upbringing is generally frowned upon as you will have an unfair advantage over the rest of the cohort.

My friends parents are maths professors, he got A* in A-level maths at age 16. Life is unfair.
There are immigrants in my school from southern/eastern europe and they studied their languages for GCSE. Same story.

How can exam boards and unis tell how much Islamic upbringing Hassan Al-Habibi [Candidate number: 49302895] has? They can't and they're not allowed to try, that would be discriminatory. For all you know Maximillion Gregory Smith [Candidate number: 0498234908] might have grown up in the middle east due to his parents work.

A native brit on the street is not going to know eveything about English Lit A-level, you shouldn't expect muslim people to magically know everything in an Islamic Studies A-level. e.g. would you expect sunnis to know everything about shia islam??
