First of all, let's see if the regulations in your school are very strict. Strict words will affect scholarships, and missing certain hours will affect graduation.

However, it is generally not so strict, not to mention just self-study at night, and this kind of regulation is generally that each college and department has its own small regulations. It is suggested to talk to the student affairs office, find out the consequences, and see if the club can issue a certificate to eliminate the record of self-study at night. In addition, if you can, you can establish some contact with the counselor. Generally speaking, it has little impact, so don't worry too much.
