What to study for I.N.B.O.

This level includes all kinds of questions including MCQs (with negative marking), True/False type passages, numericals. So the questions are of very high conceptual levels which need depth in biology. One has to deal with reasoning, negating etc. 

Cladogram making, pedigree analysis with numericals, phytohormones' actions etc. are frequently asked.

What makes it all the more difficult is the time constraint. Most people cannot finish the paper in the first attempt. And if you finish it, then you can be almost sure that you are going to score nicely.

Campbell Biology is a must, to be read in detail, taking care of all diagrams and in-text questions and end-of-text questions. The best part is that model answers are given in the book itself. I will soon upload notes for this book.

Again, to realize the time constraint, past papers are a must. They can be found here:

The students who really want to get to the national camp can try out papers of 2nd level of other countries. There is a lot of material on a popular Biolympiads blog made by my friend Martyna. It is amazingly filled. Go through all parts of it carefully. The link:
