SDN Members don't see this ad. (About Ads) Hello all, The school I graduated from used quarter units (each class taken was typically 1 unit). However, I completed my physics requirement from a state school that uses semester hours (I took 10 hrs of physics). Additionally, I may take more post-bacc classes from the same state school that uses semester hours and, as such, am interested how these courses would affect my GPA. I have searched around a bit and can't seem to find the right conversion. I believe I heard along the way that 1 quarter unit=2.7 semester hours.....In other words, the 10 semester hrs of physics I took to complete my physics requirement is actually converted to 3.7 quarter units..........My concern with this is the fact that if I had taken the year-long physics requirement at my quarter unit school, it would only be 3.0 units, rather than the 3.7 quarter units the conversion equals. As such, it would seem advantageous to take classes at a school that uses semester hours as I would seem to be able to make changes in my GPA faster (6 semester hours seems pretty standard for 2 classes but would equal more than 2 quarter units). This would all be so much easier if there was simply a universal way to calculate grades!
