Once the student has learnt a topic, he can attend a question and answer session to test his level of understanding on that topic. This CD-ROM uses a concept of randomisation, which leads to a virtually never ending permutation and combination of exercises that makes it a valuable tool even after using it many number of times. Students are randomly given 168 exercises (281 questions) out of the 672 exercises (1124 questions) in the CD-ROM, during each entry.

When the student is unable to solve a question he is shown a hint to help him think better. If he is still unable to solve the questions, detailed step-by-step solutions are provided.
