Studying for SBR with Opentuition

What is the best way to study for SBR or Professional exams of ACCA? In F levels I studied with Opentuition videos, attempted the MCQs for each chapter. Now there are no MCQs. So are we to wait till all videos are done to start the revision kit or should we try questions for each chapter from the revision kit after completing respective chapters? What is the suggested method here?
Reading whole textbook is a difficult task!
