http://www.sjsu.edu/admissions/impaction/impactionresultsfreshmen/index.html indicates that SJSU CS and CE needed eligibility indices of 4725 and 4700 for fall 2018 admission. The software engineering major needed 4200.
Since the student’s eligibility index = 3.9 * 800 + 1370 = 4490, SJSU should be considered a reach (not match) for CS or CE, but maybe match for SE.
On the other hand, SFSU is not impacted for the campus or for CS, so it is a safety.
