It's a good app.. I am not sure about whether I liked it or not but the answers are perfect
It is a very cheap app because it has no lessons summary
explained but not satisfactory.
Very good for all those students who have no elder brother to teach them.
It is the best app for student and teacher
Good for exam point of time
It's ok nice
The solution of exercise aren't in this.
Best app for students
A nice app
It is amazing
