ICCA

You can - it's not likely / probable that you'll pass. But it is theoretically possible.

But why would you want to adopt such a silly approach? even if you're not comfortable with the topics in qs 4 and 5, there are still easy marks to be gained from there. Much easier than the marginal benefit you are likely to gain from spending extra minutes on qs 1, 2 and 3.

I don't believe that students continue to ask this question when tutors / forums / chat sessions / examiners / ACCA ALL say attempt every question. Your planned route invariably results in a fail.

Don't do it!!
