UT allows the two years to be in computer science. At least the GC advised against it. Many GCs in Texas will just follow what the top publics want.
Summer Spanish 1 and Spanish 2 in school is a good idea.
Rice doesn’t have the same computer science as a FL commentary. They just say two years of a FL as a minimum requirement. Then say “ * Students admitted with curriculum deficiencies will be asked to complete the required work by taking high school or college-level courses during the summer before enrollment at Rice.”
