# ISI B.Stat and B.Math Entrance - How to prepare, curriculum, paper pattern and topicwise weightage

The BStat and BMath Entrance of ISI Entrance is ‘different’ from IIT JEE or other engineering entrances. It tests creativity and ingenuity of the problem solver that requires more than mechanical application of formulae. Many of these problems are inspired from erstwhile Soviet Union math contests and other math olympiads.

The entrance has two sections:

• Objective section containing 30 problems to be solved in 120 minutes.
• Subjective section containing 10 problems to be solved in 120 minutes

## Cut off for ISI Entrance

The cut off varies every year. However 80 out of 120 in objective section and 50 out of 100 in subjective section should put you in a comfortable position.

## Interview for ISI Entrance

If you do well in the entrance then you will be invited for the interview. Several Cheenta students have supplied problems from past interviews which you may find in this link.

## Curriculum for ISI Entrance

ISI has an official curriculum for this entrance. It can be found in the problem compilation that the institute publishes every year. The topics are similar to high school curriculum but also includes some extra ideas from elementary number theory, geometry and combinatorics. Moreover the so called ‘regular school topics’ are tested in highly unusual way. This is the main challenge of the entrance.

Cheenta has a free toolbox that you may use. Our paid programs can also be useful for long term preparation.

## Topicwise Weightage

At Cheenta, we have unofficially complied a topic-wise weightage. It is based on past year papers. Please use this information carefully as all years are note the same.

• Geometry - 10%
• Number Theory - 10%
• Combinatorics - 10%
• Mathematical Games - 3%
• Mensuration - 3%
• Theory of Equation - 10%
• Complex Number - 10%
• Binomial Theorem - 3%
• Inequality - 3%
• Logarithmic expressions - 3%
• Function - 7%
• Sequences - 3%
• Limit, Continuity - 10%
• Differentiation - 3%
• Integration - 3%
• Trigonometric expression - 6%
• Coordinate Geometry - 3%

Please note that there are huge overlaps between these topics. For example there are problems in complex numbers that may be regarded as pure geometry problems and so on. Similarly tools such as coordinate geometry, trigonometry or vectors, logarithms can be used in a variety problems in calculus.

## Books

• Challenge and Thrill of Pre-College Mathematics by C. R. Pranesachar and V Krishnamurthy
• Problems in Calculus of One Variable: (with Elements of Theory by Isaak Abramovich Maron
• Test of Mathematics at 10+2 Level by East West Press
