AA, PM, TX – combining 2 in one sitting or no?

Hi, Guys.

These are the A Exams left to me.

Based on your experience, would you recommend to combine which 2 of them? Or I shouldn’t do it at all?

I have 4hs a day to study until June. Know that PM is awful, but are the other 2 feasible to do at once?

Tks
