^Typical students complete many more credits than the min required for graduation, so looking at these ratios may not be appropriate. MIT/Caltech specifically require upper level H/SS courses, and I believe HMC doesn’t. They also require more specific writing intensive H/SS courses than HMC. All these upper level H/SS and writing-intensive courses can’t be taken on pass/fail basis, and HMC doesn’t have such requirement, I believe.
