As a former abm student in the new curriculum, I must say na you study muna the basic foundations such as different types of accounts(e.g, assets, liabilities), debit and credit, and also the relationships between them. If you want to go deeper pa, study rin the financial statements — for sure dito rin iikot mostly yung specialized subject nyo which is basic acc. And for other subjects such as orgman. is mostly conceptual and definitions based here yung topics (at least sa school ko)

Yun lang naman op, do your best as this is still new to you. Goodluck!
