Emergency help urgent

I have taken partial drop from the college to come in NIT ...

Now I didn't submitted my TC from my older institution instead I have submitted a year GAP certificate and TC from school...

Reason: I have already reported to college and submitted GAP AND SCHOOL TC because previous institution has still not provided me my TC and asking only me to receive.

I wanted to know will this create issue in future.

The previous college was not registered through JOSAA it has its own councelling but was government college

Seniors I would be helpful if you reply back your thoughts and suggestions
