If you are appearing in 2014 exam,there is ample time for you to work.
Make a list of frequent asked questions,from past papers-particularly from Essay and current Affair papers and try to clear your mind on those topics.Also, read Dawn newspaper coupled with profound magazine,such as Times,press review,economy survey etc,and when you see anything helpful,comparing to the list you made,cut that down and placed it in a file.By doing so,you will be in touch with current issue and also will have enough material at the end.
Write as much as you can and let it be checked by any English experts.This practise will help you a lot especially in Essay and precis papers.
Select books for compulsory subjects as soon as possible,Everyday science,Islamiat,and pak Affairs and try to cover them till September.
For maths part in screening test,quantitative and analytical portion of GAT by jahangir publishers,is i think enough.
These aforementioned steps will help you a lot in the screening test and also will broad your horizon.Once you pass the screening test and become eligible for written part then select your optional subjects and start preparing them.
Wish you best of luck

Thankyou so much, basically im from peshawar too. Can you please tell me where to buy the books from? (if only you could provide me the names as well)

For everyday science Ikram kashmiri,for Pak Affair,trek to Pakistan and for Islamiat laqul Mohsin.In my previous comment,that schedule of study is enough for Essay and current Affair Papers.Yes,for precis study Saddat Ali Shah book "Exploring the World of English".
All the books are available at prince book shop,in saddar.

Dogar's books for GAT-GENERAL can be studied for logic/reasoning and math. For math you can also study Barron's book for GRE because all the basic concepts of math have been explained in a very simple way.

Usually art/Humanities student study math upto SSC level, but if you haven;t studied math at all, then you need to work a bit harder. you can study math books of class-1 to class 10th but the simple solution is to study math/quantitative portion in Barron's book for GRE and dogar;s book for GAT-GENERAL as i have mentioned in my previous post.
you can take tuition to clear your basic concepts of arithematic/algebra and geometry.

plz members suggest me some guidelines regarding the preparation of current affairs mcqs
