How to choose?

From now,
I need to choose two out of three optional professional paper for my next sem subjects.
It's hard to make a decision,
After i reviewed the syllabus from the three subjects,
i found that i have interest on P5 Performance Management.
This is because it is need foundemental from management accounting and business analysis and beside it is theory plus some calculation questions.
For P6 Advanced Taxation i also not sure whether i have interest on this subject.
If i choose this subject, one of the reason is i'm learned this subject before.
For P7 Advanced Audit and Assurance, actually this subject is cover a lot of theory,
for me haiz hard to choose ar.....

Ok this is my temporary decision i will choose P5 and P7 as my optional paper or P5 and P6.
