Over 140 revision notes and 1420 questions with explanations on Number, Algebra, Geometry & Measure and Data Handling. DETAILED TEST RESULTS On the completion of each test the user is given a summary of test along with the time taken on each question. Every question can be reviewed and all questions have an explanation of the answer. PROGRESS METER An interactive pie chart displays current progress for each topic so that you can track your weak areas and retry the questions you answered incorrectly. MOCK TEST Mock test simulates the real test format. Questions are presented randomly from all the topics.
