Tesda Bookkeeping Certificate

Hello! Im starting to expand my skills set so I thought of getting the TESDA Bookkeeping certificate.

Pwede po bang mag take ng Tesda accreditation assesment even if hindi po ako nag enroll in their bookkeeping course?

Im planning to self study po kasi. Im currently in college. I took ABM in shs and I also took an Accounting course included in my college program so I have a basic knowledge of accounting din. Will it be possible?
