Personal KVPY SX preparation tips - Syllabus, Marking, Procedure

Every science student prepare for competitive exam in class 12th where KVPY SX is one of them. Many student dreams to become an astronomer and scientist so KVPY SX is what they can give. 

Well KVPY is an scholarship exam for those student who want to pursue their studies in basic science. You can give KVPY in class 11th , 12th and even in first year of basic science bachelor degree. 

If you want to give it in class 11th than you need to apply for KVPY SA whereas in case of 12th it's KVPY SX and for your first year in bachelor degree of basic science its SB. We have a full preparation guide from chapters to eligibility to all the concept you need to clear for KVPY SB stream click here to read that article as well.

KVPY SX is national level scholarship exam for class12th science student who want to pursue their career in basic science and don't forget if you are going to appear for KVPY SX than your boards are also this year only. So a proper time management and planning is necessary for this.

Before planning for KVPY preparation we need to know when exam is conducted and procedure of exam.

Selection procedure for KVPY SX:

Well to qualify for KVPY you need to know how a candidate is selected and the process of clearing KVPY SX stream.

Step: after applying for KVPY exam your are provided  you have to give Aptitude test which is computer based examination. 

Here is the trend of KVPY SX previous year cutoff:

If you are from general category you need to score 57 marks at least in KVPY SX aptitude test to qualify KVPY and general or pwd category you need at least 40 marks in aptitude test.

Cutoff of SC/ST and Pwd are always same whereas for general category cutoffs were generally high due to reservation system of India

So here's how selection procedure goes:

So you need proper time management for preparation if you want to qualify KVPY SX and for that you need to priorities your important chapters.

KVPY SX/SB paper analysis:

P.s: KVPY SX and KVPY SB syllabus and subject difficulty is almost same so below is the difficulty and info based on KVPY SB but this apply for KVPY SX as well because there is no such huge difference.

Physics section:

No. of easy, medium and difficult level questions in physics SX aptitude test:

As you can see that around half the questions in KVPY SX physics are easy and other half are of medium difficulty level whereas difficult questions are less in physics section. 

Well here is the list of topics/chapters and number of questions ask from these chapters:

Chemistry section:

No. of easy, medium and difficult level questions in chemistry SX aptitude test:

Well here No. of easy questions are more compare to physics section but medium difficulty questions are less and no. of difficult questions are more.

Well here is the list of topics/chapters and number of questions ask from these chapters:

Maths section:

No. of easy, medium and difficult level questions in chemistry SX aptitude test:

 In maths No. of easy questions are less compare to physics and chemistry whereas you will find more number of questions with medium difficulty. Number of difficult questions are also more in maths.

Well here is the list of topics/chapters and number of questions ask from these chapters:

Biology section:

No. of easy, medium and difficult level questions in chemistry SX aptitude test:

Well in biology section here you will see far less easy question whereas most of questions will be of medium difficulty and some difficult questions will be present. 

Personal preparation tips:

Well, practise makes man perfect and therefore its important that you are prepared enough to qualify for KVPY SX. Well I didn't had particularly prepared for KVPY SX rather I had prepared for KVPY SB. 

So here are some my personal preparation tip which you can use to prepare for any competitive exams. I will tell in detail that you need to each of these tips for KVPY SX in particular. 
  1. Proper time management
  2. Priorities your chapters according to weightage 
  3. Proper strategy to achieve your goals.

Proper time management:

So if you are preparing for KVPY SX then your are going to give this exam while you are in class 12th. So some key things which you need to realize here is:

  • Your KVPY exam will be held before your board in the month of November. 
  • You need to prepare for boards as well. 
  • During your interview round your practicals will be going on. 
May these all things have worried you but to counter all these, You need a proper time management. 

Here's what I would do  do to manage if I was at your place to manage time:

  • Studies common topic/chapters which are in boards and KVPY as well. Will cear basic concept of these topics and try to solve conceptual question by this at the same time I can prepare for KVPY as well as boards.
  • Study for KVPY specially for 2hrs in a day there is no prescribed time you can study whenever you want where ever you want only goad you need to accomplished is to study 2hrs daily.
  • There can be scenarios such as practical journals and everything what I would have done is instead of writing whole journals in 1 or 2 days , write small small portion of it every day from the beginning of September only by this there would not be much load of journals during KVPY exam in November. 
  • Try to solve previous year KVPY SX papers. Link to papers and solution are given below in the important link section.
Must follow this tips at least this what I would have done to clear KVPY SX. There's no need to worry KVPY test your concept only so try to focus on concept clearance as much as you can and by this you are also prepare for your boards. 

Priorities your chapters according to weightage:

Well priorities your chapters according to weightage they carry in exam. Clear concept and basics of those chapters first who carries most number of questions in exam and have high weightage. 

Here is the weightage of each topic subject wise in pie chart for your better understanding: 


So as you can see more number of questions are asked from mechanics so be prepare to have your basics cleared before appearing for KVPY SX physics and plan and priorities your chapters list accordingly.




After viewing these tables you will now have a clear idea that which chapter you should complete first and how to priorities your chapters list accordingly. 

Proper strategy to achieve your goals:

Now you know what you should prepare and when to prepare, Next tip I will tell you is to have a proper strategy in your mind from which chapters you need to solve first or which subject to attempt first and all these kinds of things.

To clear KVPY SX, smart work is also needed along with hard work.

Unlike KVPY SA, KVPY SX/Sb stream candidates have two parts in their question paper. In part 1 you need to attempt any of the three subject from PCMB whereas in part 2 you only need to appear for any two subject.

So ,Above I have given you difficulty level analysis of each subject in KVPY  SX and on basis of that you should appear for PCM or PCB but when you go for attempting part 2 you should go for Physics and chemistry only because number of easy question in both these subjects are high compare to maths and biology.

Well this depends on each individual on whether which subject you are comfortable based on their skills but this is what I will recommend you to go for physics and chemistry in part 2.

Bonus tip:

Solve previous year papers of KVPY SX. Link of paper is given in Important link section. Try to solve questions as if you are giving exam and manage your solving accordingly by this you will be able to identify your skills and have an idea of your capabilities about time you will take to cover each subject.

Important links:

So here are some of the study materials you can refer during your preparation for KVPY SX stream:

1. Last 5-year KVPY SX question papers

2. KVPY official Website
