I used it a lot while pursuing my electrical engineering degree. It's ability to solve almost any mathematical formula and to show you the solution step by step is just plain awesome. I guess it's safe to say I would not have passed some algebra and electrical engineering exams without it. One tip I have (not sure if it still works though): Buy the Android or iOS app for a few bucks to get access to the step by step solutions if you can't afford the pro subscription.
