Your apps have really saved the day, when i was in my chemistry class it really helped me understand it at a deeper level.
I got a B in that Class i never thought in my life i would get a B in Chemistry.
These apps really helped me learn Balancing chemical equations, Helped me learn the periodic table, and helped me learn stoichiometry.
I have switched to computer science and will only need 1 more chemistry class but i was glad i had it.
It really saved the day when it came to test time.
At 49.95 it is a steal.
When i got the Business and Statistics made easy it really helps me to visualize it
