The Pyramid of Marks

Why the CSE approach fails in IFoS optionals.

CSE candidates spend 8 to 10 months on an optional and operate at Levels 3 and 4. In IFoS optionals, even toppers cover only 70 to 80% of the syllabus. Just doing the PYQs properly puts you at the top.

  1. Brainstorm 10 years of PYQs
  2. Have compact notes
  3. Write 2 full-length tests

Toppers, in their own words.

The one on one by Acads faculty was very helpful. The questions were very relevant to my DAF and helped me identify my weak spots. The feedback was provided in a very pinpointed manner . Further, Sir also helped me resolve some additional doubts I had and helped frame answers for some tricky questions. Thank you again!

Talking about Forestry, I got a total of 242 marks out of 400 with a preparation of hardly 20-25 days. The idea was to keep my preparation exam oriented and PYQ focused. ACADS came in very handy for this. … at the last moment, my own short notes of both the papers keeping ACADS notes as a base were the only thing with me before going for the exam.
