Hello there! 

Greetings! 

It's good to know everything thing in a subhect but when it comes for preparing for competive exams you need to be totally exam oriented.Time is a very crucial aspect while preparing and it should be saved by avoiding unnecessary research on any topic. GATE preparation must be highly exam oriented. Reading complete textbooks for each subject takes up a lot of time and effort. It is a very good practice for enhancing knowledge but not so much when one tries to prepare for GATE in a stipulated amount of time. The focus must always be on clearing the exam and thus, the preparation strategy must be highly goal-oriented at all times. Textbooks or any such sources must only be referred for topics that one finds tough to understand from their primary source of study. 

Topics can be classified into two different types which are; conventional (traditional) areas of the syllabus and rarely asked topics. Conventional areas are those which must be prioritized since they are sure to carry the highest percentage of marks , you should focus more on these topics .

Rarely asked topics can be taken care of at the end of the subject as they can provide an extra edge, in case a question from those topics comes up. Similarly, out of numerical and theoretical topics, depending on one’s own comfort and strengths, one must identify and prioritize topics accordingly.
