Is it necessary to provide the number of backlogs even if I have cleared all of them?

Yes, you must disclose all backlogs, even if they are cleared. Universities and employers typically require your full academic history, including any failed subjects that you later passed.

Being transparent avoids issues during background checks. For example, companies like TCS specifically ask for details about all backlogs, cleared or not.

Cleared backlogs are usually acceptable, but hiding them can cause problems. Only active (uncleared) backlogs may limit your opportunities. If you have any pending, it's best to clear them before applying.
