Dropping course with absences

I'm from Arki and nabasa ko lang na up until Sept. 25 yung requesting for From6A and ngayon ko lang napasa for signing and approval.

Question ko lng is do I have to immediately go now for endorsement sa guidance? If magdrodrop po ba ng subject, macacancel out na po ba yung mga absences sa subject (3/4 na ung absences ko sa major subject na yun). Thank you.
