The CGA considers Critical Reading and Math. For the ACT, they use Math and English. They super score for both tests. Super scoring is where they take your highest Critical Reading score and highest Math score. The scores can be taken from any sitting. The same goes for the ACT except it's Math and English instead of Math and Critical Reading. Admissions tends to give more weight to the Math section of both tests as CGA is STEM oriented. 75% of their majors involve STEM. The only Humanities majors are Government (Political Science) and Management (Business/Finance).
Hope this helps!
