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.
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.
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 !
