I'd recommend it to any student who needs help. It's helpful, very very much, that would make it perfect , it really works, after i seen that people were having trouble with the app then i tried it out and it really helped me on homework then i showed my friends and it helped them too.
Just like what a great teacher would do except you get to do it at your pace. It really is helpful, especially how it shows the working out steps. Way more powerful than I expected.
