SAlaam
I dont know about Accounting and Audit and mercantile law,
However, For the compulsory, im preparing from:
[B]Pakistan Affairs[/B] (Track to Pakistan, Paksitan studies by Rabbani) but Gul Shazad Sarwar is also an awesome book
[B]Current Affairs[/B] Newspaper plus the Jehangir World Times is very informative and recommended.
[B]EDS[/B] k liyay I was reading the O-level Physics, Chem and Physics books sme1 said they would be enough, but recently ive been guided to get the MBD Series book for EDS with solved papers.
[B]Islamiat[/B] If you're giving it in English then Islam: its meanng and message by Khursheed Ahmed and Islamiat notes are v.good.
Urdu me there is this book Islami Zarya e Hayat. I was recommended that one earlier.
[B]English[/B] Raymond Murphy is very good but ye book ho ya Wren and Martin ho/ ya koi bhy book ho, jis se bhy aap k concepts achay clear hojaen. Use THAT one!!.
I hope this helped!!.. :)
