Score in computer science?
 

Mine is 62..

Aso how are you kindly tell me how you prepare the all course of computer science?

W/S
man just go through fundamental concepts of each course. There is no single book for this. You will have to consult standard course books considering the diversity of the subject. I studied silberschatz, william stallings, tanenbaum, dietel and dietel, rest i studied from internet.
Programming => classes and basics of oop
DS => link lists, bst, stack, queues etc
Networks => i had studied in detail as it was my area of expertise. you may go through osi layers, protocol headers, internetworking standards, routing protocols, other layer2-4 concepts.
Soft engg => focused on models
web => again i am strong in this area so did not focus much on it.
archi and os => os scheduling algorithms, threading, multiprocessing, and all related concepts, memory management, basics of architecture.

All the best.

kindly explain the relevent areas of web engineering
