3 vs. 4 HLs

I am trying to choose my HLs for the IB program. I want to major in Psychology so the HLs I know I am taking is HL Psychology, Biology and English. I am not sure whether I should take HL or SL French. The other SLs I am taking is SL History and SL Math Methods. What should I do?

Take 3 SLs not 4. Your total score is what matters and you can register for the AP French exam with the SL course (French SL is quite sufficient for the AP French exam).
