PREXAM is a testing tool for students to check their preparedness.
The tests are generated by selecting questions randomly from the database based on the chapters and subject you selected. That means even if you select the same combination of subject and chapters you would get a different paper every time and the questions you get would be different than what other user might have received for the same combination.
The tests are time based and total marks for the test can be chosen by the user.
Each test is followed by a solution which you can print or store for future reference. All your tests would be saved and available for review. We would soon be including the your graph of preparedness for your exam so you can evaluate where you need to work more on.
