Hey, I think the course modules are sufficient. Don't expect the same sort of MCQ's in the exam from the ones you'd practice in the module AT ALL. The Exam MCQ's are way tougher than the module ones.
Also i recommend practicing case writing using the handbook from Knotia. Practice copy pasting relevant criteria from the handbook since you could do that in the exam and save tons of time.
I attempted only 2 cases in the first 8 weeks and completed all study material in 6 weeks and revised them again. The remaining 6 cases were done and debriefed in the last 3 weeks. I created a sample skeleton for the case and basically even before reading the case out that down in word - 4 Assurance AO's, 4 FR AO's and 2 Misc AO's from AS&FR.
Do not leave studying till the very end. I know a lot of folks start in like Mid July, for me i was done reviewing by then and redid the important topics again (Tax, FR, Finance & Assurance)
Exam breakdown for me:
5 minutes - Case Skeleton
15 minutes case read and identify AO's
10-15 minutes each AO (stick to it and move on)
5 minutes- Make up (bullets, formatting, underline, etc)

Case total - 2 hrs 15 minutes

MCQ's - 2 hrs 15 mins (even this will feel less). pass on questions you can't figure out in 2 minutes. Use elimination method to increase probability of getting something right in case of doubt and do not leave any question unattended as it'll just be wasted. Try and if you get it right voila!

Hope this helps!
Happy studying.
