OT enough for cert in BA?

Hello,
Could someone please tell me if the OT lecture notes/lectures enough to be able to pass all çert-in-ba exams?

also, is it possible to pass and get the cert in business accounting within 4-5 month? I have previously passed all acca fia and fundamental exams, but due to a personal reason have not opted to get exemptions for the cert in ba.

I would really appreciate the help. OT has been, in the past ,amazing for me. Passed all my acca fia/fundamental exams using ot.
