    Order of importance to study for passing the exam....
    1, Theory of computation Computability, complexity analysis ( important since others may ignore it and only few will answer it correctly so opportunity to score above others)

    2, Compilers and system programming( language processors ,lex anlsis, etc) ( important since because of the same reason as above

    3, algorithm design and problems different methods  for algorithms....(important since if u studied definitly you have a chance to beat the averages)

    4, Computer architecture, pipe-lining etc....

    try to understand and know the basics of these first and study it well it will help you go more....


    of course the others OS,DS,Digital,and other in the syllabus also important but it will be under standable by average people easily so don't avoid them any way i know that all have somewhat basics about these subjects....
