Dear aspirant hope you are doing well...

Fail in one or two subject  out five subject is not consider you fail for the whole course but you have to pass in Re-examination Or retest otherwise you consider as fail for the course /year back. This is happens in most of cases but i can guarantee it. Because there are many special cases too. You should read the  guidelines issued from your colleges or contact to examination authorities .
