What to do ? Prepare for competitive examinations from your schooling onwards – it will help you increase your mathematics speed, verbal ability (word power and grammar), reasoning skill etc. Later you may appear in a variety of aptitude tests – and there is a possibility that you will get good score in these tests. Read good articles and prepare yourself. There are many books on vedic mathematics, prepare from them as well. 5 DECEMBER 09 www.afterschool.tk 16
Is there any fixed syllabus for competitive examinations / aptitude tests ? No – it is a test of your mind power – your ability to take decision, your overall ability on the basis of your studies from schooling to date. So there is no fixed syllabus. The best idea can be that you may go through last few years' papers and identify your strengths and weaknesses and prepare your strategy. 5 DECEMBER 09
