which JC is better?

MJ or CJ?
why?

Which JC would be the best choice with a L1R5 of 10, raw, with a bonus of 2 (so it’s 8 ) for a student who wishes to take economics and knowledge and inquiry. The said student would probably pursue a course in the financial field for university.

Thanks

My son just received his O level results. It’s an 8 (already with bonus)

We’re trying to find which JC he’d be most suitable for and where he has the best chance to enter and finish. He’s not the type to study very hard and he really wants to take KI (Knowledge and Inquiry)
Which JCs can you recommend to me for aggregate of 8, appeals aside
