Need help deciding between MA2 and FMA?

So here is my dilemma. I have sat F2/FMA exams about 6 times and the highest mark I got was 47%. I have the following two exams left to complete the FIA Diploma Level:

MA2 Managing Costs and Finance
FMA Management Accounting

I plan to automatically move on to ACCA Level 2 after i complete FMA as I do not necessarily want the FIA Diploma.

I would like to know if I should only focus on FMA since it covers what is included in MA2 or should I do MA2 first even though I think its a waste of money to pay for the exam seeing that I already plan to do FMA?

I plan to sit F2/FMA again in December 2019 but should I do MA2 before that?

What would be the benefit if there is any, to sit MA2? I think the only reason to sit MA2 is if I want to get the FIA Diploma.

I am studying using FMA/F2 virtual classes.

I would greatly appreciate any kind assistance.
