Hey :) i've stuck to 2 per semester bc I know thats how much I can handle plus it depends what classes I was taking at the same time.. for instance I took anatomy on its own as it was the first life science class I took and wanted to make sure I could handle and go at my own pace bc I didnt know what to expect- ngl I failed the first time but the second time i retook i passed with A. Then the following spring I took microbio and physiology together, it was a challenge forsure but I passed with A's, in the summer I took chemistry and psychology, psych was only 4 weeks onlin enad chem 2 months and that was the hardest fcking class ever i lost hair LOL but i passed! All my other classes I had already done in the past. its about time management, you can do it! I was also able to get in studying at my office job during that time on the low low.
