Recommendation letters

Is it ok to get recommendation letters from two math/science teachers or two get it from one math/science and one humanities teacher. I know some schools such as MIT require both math/science and humanities, but what about the colleges that don’t specify like nyu, uMichigan or uMaryland, would they have any preference?

If colleges don’t specify, then you can send in 2 math/science recs, as long as you’re sure that you can’t get as good a rec from a humanities teacher.
General rule of thumb: If a school doesn’t require 1 math/science and 1 humanities, then 2 good math/science recs will always be better than 1 good math/science rec and 1 generic humanities rec.

MI only accepts one LoR – choose the most supportive
