A free program for Android, by Inducesmile.com.
This app is an offset of Inducesmile.com’s more popular Total Chemistry app.
If you are preparing for big examinations like WAEC or NECO, or perhaps even simple Chemistry tests for high school, this app should help you bulk up on cognitive power by providing you with a comprehensive set of tests – the modes ranging from objective to theory.
The challenges found in this app were adopted from the official WAEC test, which should heavily condition your mind with a similar level of difficulty.
The tests come with included solutions, which are elaborated in detail for your benefit.
The modes are split and organized into categories – one for the Chemistry Theory type of inquiries, the other for the more objective type of challenges. A dictionary is added as bonus.
