  • The trick is to start WBCS Prelims & WBCS Mains preparation together at the same time .One should not wait for the result of prelims to start preparing for the mains as it would be foolish thing to do.
  • Many subjects overlap with prelims such as: Indian National Movement, Geography, Science, Current Affairs etc. Hence one just need to revise again.
  • Don’t burden yourself with too much books. Study what you will be able to retain before the exam.
  • Keep yourself cool!!We understand expectation of your family members have increased since your prelims are cleared.
