If you have cleared one subject and failed in another in your supplementary exam, you may be allowed to move to the next year with one subject pending, depending on your university's rules. However, you may need to clear the failed subject within the given time frame to avoid delay.

HEY THERE!!

According to BDS rules in major Indian universities and the current guidelines:

• If you failed in 2 subjects in your 2nd year BDS exam, and then cleared only 1 subject in the supplementary exam (still failing in 1 subject):
• You are allowed to carry over only one failed subject to the next academic year in most universities.
• You may attend classes in the upcoming year (3rd year), but you need to clear the outstanding failed subject so you can sit for the upcoming year's university exam (i.e., the 3rd year BDS exam).
• If you fail more than one subject, you cannot be promoted and will have to wait and clear the subjects before proceeding further.

In your case:

Because you now have only one failed subject after the supplementary, you can proceed to the next year (3rd year) with that one subject. You don't need to wait for 6 months or repeat the year, but you need to clear the failed subject before you can appear for the 3rd year BDS university exam.
