SSC GD Exam Prep: A SSC Exam Preparation App for the General Duty Constable (GDC) and Other Bank Jobs.
The app contains a lot of questions that are asked in the SSC GD Exam.
It provides the answers in the form of a series of charts that are presented to the user in a very clear and easy-to-understand format.
The user is also provided with a set of notes that are taken from previous years' papers and also contains the information about the selection criteria.
As the user progresses through the levels of the app, the tests become more and more challenging and difficult.
