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?
Hey,
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.
Thank you.
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.
Hello candidate,
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??
Hello student
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.
