Quick and effective practice

I really do love this app. As a way to study whenever I have a minute or two free, standing in line, on the bus, when I wake up, it is perfect. I can feel the reinforcement at work. The only thing that would make it even better would be the ability to focus specifically on areas where I am weak, like very similar hydrocarbons, all together instead of mixed in. But at least I’m getting regular reinforcement of everything in between! Definitely recommend for any chem student.

Just Right

Love this app. Fun, ease of playing that makes it interesting and a way to feel one way to spend time and see new things that have been right under our noses all the time.
