walked into the aptitude test with absolutely no expectations, though I'd heard notorious tales of the difficulty it posed to students in previous years. Its pretty simple actually - you go in, you see the questions on the screen, you read the instructions clearly (I skipped this step and realized that there was negative marking after I finished the math section and couldn't do anything about it) and you start furiously scratching pen to paper. You have ample time to solve all the math (a notch above regular aptitude tests and far below CAT levels, testing your puzzle solving ability and math skills equally) and verbal (analytical) questions that are given to you. Following this is a short section on programming (separately timed) that tests your ability to process code, and understand it, not merely find errors in syntax. This section is slightly difficult for those with absolutely no understanding of programming (C/C++), as understanding the syntax is key to understanding the question, and solving it. Note that you will not get more than a minute a question, sometimes even lesser depending on revisions to the process. I would suggest you spend the first minute running through the math section, quickly solving those you've practiced for/expected. There will be a few difficult ones in the set as well, don't spend more than a minute on them. Remember, you are not writing an exam to score a hundred. The analytical verbal section, believe it or not, actually requires you to think, so save some time for that. Personally, I attempted all the math questions (before I read the instructions, D'oh!) and three or four of the verbal ones
