Whole grade system does not subtract GPA points based on minus or plus grades, and some other universities awards A+ grades a 4.3 GPA. But NMSU departments were allowed to opt out of the fractional system, leading to different grading throughtout the university.
Some professors follow the fractional grading, where they will give you an A-, and other professors just tell you that they don’t believe in assigning minus grades or plus grades. This is entirely up to the professors. This is not beneficial for most of the students. ASNMSU is thinking to circulate the paper petitions on campus to prove the student support for reforming the system and there will also be a link to sign the petition on the ASNMSU website.
