School hold credentials for board exam

hello atty. i want to ask on what can i do about my school, they made us sign an affidavit before we graduate last march that we must attend a review to be assist by the school before we review in an intensive review. it says that if we fail to pass the mock board we are not allowed to attend the intensive review. another problem is I can't afford to take the review which was pushed by the school so I plan on working to earn for my intensive review. the problem here is they might not allow me to take my credentials and apply for board exam.
i hope you can help me with this issue. thank you

What course is this and what school?

Appeal your case to the school administrators first, then escalate your situation until it reaches the highest position if resolution was not met. Document everything in written form.

If there is still no resolution after going to the highest position, go to the CHED and take your case there. Seek their advice, as well, on what to do best in your situation.

Good luck.
