The CSU Mentor EI calculation is incorrect. CSU’s only used SAT Math + CR in their admission decisions so that is actually what is meant by SAT total. So the EI of 3450 is correct not the 4000. My posted formula is correct. The CSU Mentor website has been notified of the so called typo but if you look at the explanation of the EI, the site does state::::: The CSU does not use the SAT Writing section or the ACT Writing score to calculate the CSU Eligibility Index::
Your CSU choices are many. SDSU/Cal Poly SLO/CSULB/CSU Fullerton/Cal Poly Pomona/Chico State will be Reaches but the other campuses are all possible. SJSU is the only CSU that publishes their EI cutoffs for each major, so you can use their numbers as a guideline.
