12 compartment student take admission in any college of b.tech. after complete compartment exam.

Soham sengupta 19th Mar, 2020

Hello,

actually it is not possible to take admission in any college of BTech after just completing your 10 + 2 compartment exam. You have to  give the exam of of any joint entrance examination for  engineering or similar like this. You have to pass on this examination and if you have a good rank you can take admission in good colleges. Don't worry if you have not a good rank you can take admission in private colleges also with low ranks also.

Hope this will help you.

Im fail in 12 last year. in this year Im private candidate of cbse 2020 . if i fail in one subject. can i give compartment exam

Rehan Alam Student Expert 17th Mar, 2020

Dear Aspirant,

Compartment is an extra chance to appear for the exam which you might not be able to qualify in the first time. Compartment is given if you are fail in only one subject, so yes if you fail in one subject then you're allowed to give compartment, however, if you have fail in more than one subject, then it is considered as fail.

Hope this helps. Thank you.

goodevening, I Ajaykumar, What if I got failed in 2 subjects out six subjects. will i get compartment!

Neha Kanwar 13th Mar, 2020

Hello Ajay,

Yes this is true that if you fail in any of your subject you get compartment and have to reappear for the examination.

As per your query you asked if you failed in 2 out of 6 subjects so it is not about 2 subjects if you fail in even one subject then you have to give the exam again to clear it out.

Good Luck !

cbse class 12th ki compartment ki marksheet pe all (5) subjects ke marks appear (printed) hoge ya fir .only jis subject mai compartment di hai usi 1 subject ke marks printed aayege?

Yash Dev Student Expert 8th Mar, 2020
Hello student on the compartment result only one or number of compartment exam results are printed not all results will be printed like normal results.
Rest of the results are printed on your board examination original marksheet.
(if you've given compartment examination in only one subject then only that one subject results will be published).

Feel free to comment if you have any doubt
Good luck
