Hello,

Maths and English form the crux of SSC CGL, so you have to be exceptionally good in both these subjects to crack the exam, the reason being both comes in first as well as second stage of exam.

Be thorough with the syllabus, you can take a print out and keep beside your study table.

Make a timetable, devote time to subjects accordingly.

Solve Previous Year Question Papers, Mock Tests and Test Series

Analyze and evaluate your strength as well as the areas you need to work on further and proceed accordingly.

Read only one or maximum two books(if only required) for each subject, one doesn't have to study various books for one subject. This is one of the most important rule to crack any exam, make your resources limited but study thoroughly,

Read any newspaper The Hindu or The Indian Express, not just to be updated with current affairs, but it will also help in English Section, and specifically for this, focus on Editorial part.
