<p>Don’t know where you are getting info about colleges generally wanting one math, one science, and one humanties. To begin with no college that requires SAT subject tests requires more than two; two colleges, Georgetown and Johns Hopkins, which do not require subject tests, recommend three. For those that require or recommend subject tests, you can usually submit any tests except that if you are applying for engineering and sometimes science you need to submit a math and science; also MIT requires a math and science from all applicants and Caltech requires math 2 and a science from all applicants. In other words, as far as I know you don’t have to have a humanties test to meet any college’s requirement for subject tests. Some would recommend that if you are applying for English or history that you submit the corresponding subject test but even that is not required.</p>
