Pravat Kumar Hati has cleared the IIT JAM Mathematical Statistics (MS) 2021 Entrance Examination with a Score of 53.67 and an All India Rank (AIR) - 22.
He shared with us how he prepared for the IIT JAM MS in an interview with the Cheenta Statistics and Analytics Department. This interview will take you through the preparation journey of Pravat for IIT JAM MS 2021 and can help you with some insights that you can utilize for your IIT JAM MS preparation.
When did you start preparing for IIT JAM MS?
I heard of JAM when I was in my 2nd year then I checked its syllabus and some of the past year's papers. I found that topics that are in JAM are not something different from our college courses. So, I decided to focus on College courses and develop concepts on topics as much as possible. For that I followed my college lectures and some standard books like Rohatgi, Casela, etc. And after puja (i.e after October). I decided to solve varieties of problems and previous years' papers which are kind of JAM-type problems.
As I told you initially. I focused on my College course which helped me to develop concepts on most of the topics that are in JAM and some topics which are not covered in college yet at that time, I tried reading those topics from some books or online resources. And at the end of October, I completed covering the syllabus of JAM. Then from November, I started solving varieties of questions mainly MCQ type from various questions papers and other sources which are kind of similar to JAM questions, and continued this till mid-December. From mid-December, I started solving questions in a time-bound manner. Alongside solving problems, I sometimes revised theories and all and took some mock tests on previous years' question papers (3 or 4). This continued till February.
In the last 3 months, I thoroughly solved problems mainly MCQ's of different entrance exams ISI, CSIR-NET (not all some selected topics ) along with previous years' problems of JAM starting from 2009. While solving them sometimes I realized that I needed to brush up on some topics of 1st and 2nd year, so I went back and revised them when required.
What did you do in the last 1 week?
In the last 1 week, I gave mock tests on papers of the last 2 years of JAM and recapped some formulas and relationships between different random variables which are commonly used while solving previous years.
What did you do on the last day?
Nothing actually. Just chatting with friends, watching cartoons, and spend the rest of the day sleeping.
Books you may refer to the corresponding topics:
Combinatorics and Probability
1)An Introduction to Probability and Statistics by V K Rohatgi
2) First Course in Probability by Sheldon M. Ross
1)Introduction to Real Analysis
2) Mathematical Analysis by Malik and Arora
1) Linear Algebra by Rao Bhimasankaram (May find it difficult if so then refer to the 2nd one)
2) Linear Algebra by S.K. Mappa
1) Casella Berger Statistical Inference
2) V k Rohatgi
Any resources/books/courses to practice problems for/like IIT JAM MS examination?
1) IIT JAM MS previous years paper from 2006 to 2017 left last 3-4 years paper for mock test.
2) Try previous years paper on ISI, CSIR NET (These will help you level up and increase your skills in the MSQ portion)
3) May see HCU papers too
4) Cheenta Mock Test Series
1. Sequence and series (different kinds of tests for Series)
2. AM-GM inequality
3. Basics questions come on Linear algebra
4. Focus on Eigenvalues and Eigenvector and system of linear equations
5. Relationship between various random variables
6. Inference (scoring).
What is a good score to get in IIT JAM MS?
It varies from year to year. In general 65+ is the safe score, I guess.
How did you attempt the question paper? How should one attempt the question paper to maximize the marks?
My strategy was to attempt MCQ first as they carry negative marking, then move to NAT after doing half of NAT, shift to MSQ, and then again NAT. But this strategy didn't work in the exam I did half MCQ then half MSQ and then NAT. After finishing all NAT again, I shifted to MCQ and finally ended with the remaining MSQ. I think everyone should have their own strategy of attempting and this, he/she will get to know while giving mock tests or practicing previous year papers.
How did you manage your time during the exam?
Time management comes with practice within time, giving the last 2-3 mock tests on previous years' papers helped me in this.
