how does Harvey Mudd look at IB

I am a current IB student. I am very interested in applying to Harvey Mudd ED. I would like to know how does Harvey Mudd look at IB. Does it consider it to be challenging?

Any Mudders are people who know, please help me? Does HMC have many IB students?

Also, what might be a good IB score out of 42 points for HMC.

I currently get 40/42 with 7s in Physics, Math, Chemistry Higher Level. Is this good or competitive enough?

I really need help as I want to decide whether I have a good chance for Harvey Mudd ED. I have ACT 34 and SAT 1550.
And, SAT 2 Math Physics and Chemistry 800, 800, 790 respectively.

Most US colleges consider IB challenging and rigorous. Your ACT and SAT scores are in the HM midrange.

Do you get grades?
