I was forced to use this program in my college for chemistry and oh my God, I can't think of a worse program a college forces you to work with. I could ramble on and on about this program, but it will belittle you for the littlest things. Like, you could get an answer correct, but it will mark you as incorrect just because you wrote 3 instead of 3.00. Terrible.
Tip for consumers: Colleges need to get their $#*! together.
