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.

The acads IFoS Priority Matrix

Study quadrant 4 first. Then stop worrying.

4In PYQs, in syllabusFocus on this

Everyone knows it matters; hardly anyone does it diligently. Finish this before you look anywhere else.

3In PYQs, not in syllabusDon’t worry about it

One or two questions a year come out of nowhere. They can’t be predicted. Period.

2In syllabus, not in PYQsCan be skipped in IFoS

Relevant for CSE, but in IFoS you can leave it for the end without losing much.

1Not in syllabus, not in PYQsAvoid at all costs

Obvious, yet many coaching institutes make candidates study it. It can cost you an attempt.

Species, the acads way

Five techniques for tree species.

Replicability

5 or 6 points can be reused, with little change, for almost every species. Memorise them once.

Inheritability

The species in the syllabus fall into 4 or 5 groups with similar traits. Learn one, get five free.

Mnemonics

Finding facts hard to remember? Everyone does. Memory tricks make them stick.

Maps and diagrams

Sometimes a map fills half a page. We help you prepare them well.

Linkage

Link species to other parts of the syllabus to generate extra points.

Narendra Pal Singh · AIR 47, IFoS 2025

242 out of 400 in Forestry, with 20 to 25 days of preparation.

“As most of us get very less time to prepare for 2 optionals in 2 months, I would strongly suggest making your own short notes out of the material you read, while keeping the PYQs as reference. Identifying the micro themes is essential for this purpose. Remember, it is not just the hard work which gets you into the list, rather a smart hard work and ofcourse a little bit of luck”

Results

In their own words.

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.
