How to Prepare for NCERT CBSE Class 12 Physics?

  • Try to give answers using pictorial or graphical representations as this way is more appealing and understandable.

  • Students are advised to practice numerical and derivations daily. As the basic concepts must be clear for scoring high

  • Candidates should learn the S.I units for all physical entities. This will make it easy for them to solve numericals.

  • Prefer making a list of derivations, formulae, and experiments so that students may go through them frequently. This will help them to remember the formulae well.

  • While solving a derivation, try to understand the logic behind them. Understanding the concept behind the derivation will help the candidates to broaden their technical knowledge.

  • After finishing the syllabus, students must solve questions from CBSE 12 sample papers and from books like Exam Idea in Physics.

can I fill improvement exam after 1 year gap . I was unable to fill form this year

Ayshi Ghosh Student Expert 28th Oct, 2019
I'm sorry but a dropper after class 12 th can not appear for improvement exam. You can only appear for improvement exam in the year after you have passed your boards. However, do not worry in most sectors marks do not play a major role nowdays. All the best!

Is there any source for class 12 science

Anupam Kumar Student Expert 21st Oct, 2019

Hey there

Your question is incomplete i guess. But still if you want to know about books for class 12 them for maths you can refer rs Aggrawal or r d Sharma. For physics Pradeep's physics and hc verma. For chemistry NCERT is good and enough but still you can read Pradeep's chemistry for boards.

Good luck


Ive failed CBSE class 12th twice (2018 and 2019), Im going to write class 12th boards in the year of 2020. Will I be eligible for JEE advanced 2020 and 2021 (after I clear Mains obviously)? Also is it necessary to give the first of two Advanced exams in the year of you are passing class 12th?

Aditi Amrendra Student Expert 30th Sep, 2019

As per JEE mains criteria, Candidates who have passed class 12 or any other equivalent exam in 2018 or 2019 or those who will be appearing in class 12 or any other equivalent examination in 2020 will be eligible to appear in JEE Main 2020. Those who have passed class 12 or equivalent examination in 2017 or before and those who will appear in 2021 or later will not be eligible to appear in JEE Main 2020. Aspirants who have appeared for their class 12 in 2017, failed in 2017 but have appeared again in 2018 and passed are not eligible for JEE Main 2020.

I hope this helps.

can i apply for cbs e 12th board as private candidate . as i have passed my 12th board in 2018.

Afreen Anjum Student Expert 25th Sep, 2019


As your query is about private candidate in CBSE .. as there are many condition or eligibility for private candidates in CBSE you have not mention here if you are passed in 2018 and why want to apply for private candidate ....

so to know about the private candidate eligibility and guidelines and about the condition where can a candidate apply for private candidates go through this link where you can clear your doubts:

All the best!!


is the cbse improvement exam giving students answer sheets will be checked like regular student answer sheets (according to marking scheme ) or some hard checking is there?

Aditya kumar Student Expert 23rd Sep, 2019
Hello there!


There's no hard checking or something for cbse improvement exam student, the answer sheet checking is pretty normal like regular students answer sheet as students who appear in the improvement exam has to face the same question paper as that of regular student's question paper and teachers has to follow the same marking scheme as prescribed by the cbde whether it'sthe answer sheet of regular or improvement student.
