Biochemistry and Physics Courses

Which biochemistry courses are the best in terms of for MCAT and professors? I am between:

BIOMG 3300, BIOMG 3310-3320, BIOMG 3330, BIOMG 3350, and NS 3200. Is the summer biochemistry course (BIOMG 3330) better?

And I was thinking of taking PHYS 1101-1102 either my junior year or summer before my junior year so I can also do research if I stay over the summer. Is the summer option easier or should I stick with the normal schedule.

And do I have to take genetics for the MCAT or med school? Or can I take a physiology or cell biology course instead. I am thinking of transferring to HUMEC (HBHS) and genetics is not required, but it says recommended
