Junior Schedule

Hi, I’m really unsure about what I should do for my junior year schedule. I’m currently taking all honors class with one AP and I’m taking pre-calc for math. It’s not a lot of work and I find all my classes easy. I want to go into scientific research. Next year is the first year of the IB DP at my school and I don’t know what to do.

Schedule 1
AP Comp
APUSH
AP Calc BC
IB Physics HL
IB Spanish sl
AP Bio
gym/elective

Schedule 2
IB DP
literature sl
history of the Americas sl
spanish sl
MAth AA hl
physics HL
bio HL

Do these look like soild schedules? Also what looks like my best option? Math is a huge factor

Does anyone know how the first year of diploma programs go?
