Previous years cutoff trends
CSIR NET Cutoff mark is decided by the officials based on various factors
There is no separate cut-off marks for PART A, B and C!!!
TIP 1
FACT
 Syllabus is very vast, you cannot cover every topic.
 Every year questions are asked from few certain topics.
What One can do?
 Take Previous question papers (2011-2019) and analyze them
for atleast 15 days.
 Give more time to build up a strong strategy than learning.
 Mark the topics according to priority – May be use a color
code  Green (High); Blue (Medium); Red(Low)
TIP 2
FACT
They do not ask complicated questions. They ask
questions on simple concept.
What One can do?
 Clear your basics.
 Focus on actual basics first, then delve on deeper
study.
TIP 3
In PART-B : Don’t waste time on a single question.
In PART-C : Analyze and Answer – Try to read the
question twice or thrice to analyze.
TIP 4
Guessing is not always harmful. Sometimes it’s a good idea
to guess the answer, but wisely.
(Not applicable for PART-A !!)
TIP 5
FACT
There are certain topics in CSIR NET for which we can
not learn the basics, we need to mug up.
What One can do?
 Make a table of such topics and read them daily.
 You can also record them and listen when ever you
feel like.
Common mistakes during Preparation
 Not preparing consistently
 Not making proper notes
 Referring too many books
 Doing Ph.D. on a single topic
 Reading every book madly from page to page
 Daydreaming
 Just reading but not thinking
 Going directionless - not preparing according to the syllabus
 Feeling Isolated
 Following the Quote “I will study in a focused manner from tomorrow ”
PART- B & C Units Weightage – Physical Sciences
Most Important
Classical Mechanics
Electromagnetic Theory
Quantum Mechanics
Compulsory
Thermodynamics

STEP 3 - Time Management
 Don’t Avoid CSIR-NET Part A Syllabus
 Give Daily 1 -1.5 Hrs
 Revise the important topics 15 – 30 Minutes Daily
 One could spend a month for the preparation
 In general , 30 Minutes a day / 3 Hrs per Week
Best Strategies
 Objective Approach
 Rejection Approach (Eliminating 3 options out of 4)
 Selection Approach (Choosing the Single Correct answer)
 Read the Questions and Options Carefully
 Choosing the Right method (Least time consuming)
Mathematical Direct Method, Logical Direct Method, Elimination by Substitution,
Eliminating by Analyzing the Options, Elimination by Selected Statements, Elimination by
Related Options, Backward Induction, Trial and Error method, Visualization, Scale it and
Measure it Method, Taking examples etc.,
 Time factor (Not more than 2 minutes/question) – Maximum 30 Minutes for 15 Questions
Best Strategies
 Choose the Right Questions ( Easy 7-8 ; 5-6 Medium; 6-8 Difficult)
 Finding the Catch in the Questions
 Choosing the Starting Points – Logical Reasoning
 Get the Apt Questions – Locomotive problem for example (Emphasize is on Aptitude &
Reasoning than accurate and speed Numerical Skills (Bank PO etc.,) !!)
 Never Attempt Tough Problems at First
 Always Start With Solving Simple Problems (It will aid in boosting confidence)
 Use Smart Preparation Techniques (Analyzing questions and answers more closely while
solving previous year question papers ; constructing mind maps, mnemonics etc., while
preparing short notes)
Study Plan
 First, analyze the complete syllabus and previous year question papers of CSIR UGC
NET General Aptitude, Part A. Make a list of your Strong, Moderate and Weak topics.
With this, you will get an idea where to focus more, while preparing.
 Self-Analysis – Fix Your Priority in order of their importance
For self-examination, you should divide your Subject Expertise into 3 categories
according to the syllabus such as Strong, Moderate and Weak topics.
Strong Category: Easy category covers topics in which you have knowledge about
the topic, and you are confident enough to solve the questions.
Moderate Category: Moderate category includes topics that require a little
modification and practice.
Weak Category: Topics that fall into the difficult category which require preparation
from basic level and more practice, mostly your weak area.
This process will give you a proper analysis of your knowledge and will define your start
towards the preparation of General Aptitude, Part A.

How to Start?
• Start your preparation from Non-Practical Units (Non-Verbal Reasoning, General
Science) as they are less time consuming and scoring
• Units like Data Interpretation, Mathematical Reasoning and Aptitude, Logical
Reasoning require Recurring Practice of Questions at least twice a week
• Give equal importance to Numerical Ability and Logical Reasoning units, since both
units are most important.
• Go through your Basic Concepts of Mathematics (Ratio & Proportion, Average,
Percentage). Data Interpretation is generally based on Statistics (Basic
mathematics Concepts from Class 10th) so you must focus on statistics part which
will help you to perform well in Data Interpretation.
• In Logical Reasoning, most of the questions are based on simple concepts for
Directions, Venn Diagram, Odd One Out, Blood Relations and Non-Verbal
Reasoning, by them you can score more in less time.
• Some of the topics require regular practice like Seating Arrangements, Coding
Decoding and Series Completion so to solve them follow basic rules and tricks
• From Statistics, Questions will be based on group or individual data so go for the
concepts of Mean, Median and Mode while remembering options since many
answers you can make correct after checking options only
• Never Memorize a formula blindly. Try to know the concept behind it. Sometimes
they twist the concept in a question so merely memorizing formula can lead to
wrong answer.
Learn  Practice  Revise  Test Analyze
• Knowing is one thing but practicing really cements your logic and increases your
speed and skills
• Give as many mock tests as possible. Feel every test as your final exam and try to
score as much as possible. Learn from your mistakes that which kind of problems
you are comfortable in and which kind of problem takes more of your time.
• When you start any topic, always start with the basics, divide the sub-topics over
time intervals and take a break of 10 mins between any subtopics to recall the
portion you studied. This will help you absorb better because it gives your brain
time to absorb the fundamentals and concepts
• When you complete any topic, practice the solved examples and make short notes,
it will help you in the last time preparation. Any Unit completion shall be followed
by practicing questions related to unit. Revise the topics again. Check your accuracy
as well as your speed.
“You don’t have to be great to start, but you have to start to be great.”
• When you have covered any unit, then just revise the short notes and give a quick
practice to solved examples again, without looking at the solution. After that,
Exercises in the reference material shall be tried by allotting it a maximum time of
3 hours. Assess your score and work on your mistakes & weak topics.
Note: Same method is recommended to follow in all units.
• Once you are done with the whole syllabus, it’s time to assess our true level of
preparation by giving a shot at MSP (Model Solved papers). Revise the short notes
and start practicing Model Solved papers (3 hours for every paper). Check your
answers and calculate your marks to get an idea of your accuracy and speed.
• Note down your mistakes and next day, revise topics related to mistakes, again try
to solve the questions you were unable to solve.
“Push Yourself, because no one else is going to do it for you.”
• After solving all MSPs, Similar approach shall be followed in PSPs (Previous Year
Test Papers). Compare your marks with cutoff of that year.
Note: While solving PSP, note down the tricks which have been used to solve
difficult questions.
“Smart work always pays better than hard work”

10, 11, 12….99 – 2 digits (90 x 2 = 180)
2019 – (189) = 1830 ; 1830/3 = 610 ; 9 + 90 + 610 =709
100, 101, 102 …. 999 – 3 digits
Ans : 3 [(1 x 9) + (2 x 90) + (3 x 610) = 2019]
