How to Prepare for NCERT CBSE Class 12 Physics 2020-21?
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.

Questions related to CBSE Class 12th
Hello sir/maam, in this current situation there has been some news that class 12th cbse exam will be cancelled and the marks will be calculated on the basis of internal markings in that case I fear that my percentage will drop and I wouldnt get my dream college. What should I do?
See as of now we cannot predict anything about class 12th board examination because these exams have been already postponed till further notice and till now there is no any further decision regarding the new dates or any cancellation so we have to wait till June because in the month of June some decision is expected on CBSE class 12th board examinations.
Don't worry for marking because if the exams will be cancelled then some altrnative would be given as given for class 10th that if any candidate is unsatisfied with his/her result then he/she can appear for an examination which will be conducted when the situations become normal so like this any alternative can be introduced for class 12th as well but till now there is no any notice regarding any cancellation or further postponement of class 12th board examinations.
You can get the latest updates about CBSE examinations from the official website given below :-
I hope this information helps you.
my score is 111 marks on 18 th march morning shift. I belongs to OBC category what will be my percentile according to my shift and expected rank?? Also pls suggest some colleges on this score I am from maharashtra.
If we go through the analysis of marks Vs Percentile Vs rank for JEE-Main 2020 then according to the marks mentioned by you in the question your percentile is expected to be in the range of 94.07 - 96.21 and your rank is expected to be in the range of 51150 - 57500, you can check out marks Vs ranks Vs Percentile from the link given below :-
You can also use JEE-Main Rank Predictor to predict your rank :-
So on such rank and category you have chances to get the enlisted NITs :-
You can check out previous year's cut-offs from the official website of JOSAA as given below :-
To have a list of all those colleges which you can get based upon your marks, category, and state you can use JEE-Main College Predictor:-

I hope this information helps you.
I m in 12th PCM (CBSE) I have not given the pre board exam, and my school is threatening me that they will not give me those marks which are going from school. But i think the marks are given by the external examiner only on the basis of practicals which carry 30 marks.Am I correct?
In every school pre boards are a mandatory thing to give before your boards. It is a kind of sample test to check your preparation before your actual board exams.. Some schools also have rules for student to pass in the board exam in order to get the Admit Card.
Yes the marks are given by the external. But it's no loss if you talk to the school authorities calmly and come up with a solution to cope with problem.
All the very best for your Board exams.
I am in 12th PCM from CBSE board, and I am not giving the pre boards which have been started from tofay in my school because my JEE is on 25th. And they are saying that, they will not send those 20 (each subject) marks which will be going from school. What should I do.
If your JEE Mains examination is on 25th, definitely go and attend examination with full preparation.
Now, regarding the pre Board examinations in your school you can tell them in advance and ask for their permission and the School authority cannot restrict you from attending any examination.
Hope that this information was helpful for you.
All the best for your examinations!!
I passed I 11 in 2020 and want to take admission in class 12 as a regular candidate and Im from CBSE... can I take admission AS a regular candidate??
Your admission in 12th class in other school as a regular candidate will be possible if your parents transfer from one City to another city due to service or business. Your health problem is bound to change your city for you have to get regular treatment for unavailable reasons of ailment.
Your admission will be provincial and will be subject to the approval of CBSE board.
For this reason you have to submit a written affidavit on a 20 rupees stamp paper by your parents showing all the valid reasons for it. You have to submit documents like 11th result card ,11th registration card , document of your parents transfer due to service transfer or business transfer.
Hope this will be helpful.
