CBSE > Class 10 > Mathematics | CBSE Board | Homework Help

The senior secondary level of school education in India can be the most defining period in shaping the higher education options & career choices of a child. What stream you need to choose after class 10 – science, commerce or humanities - is a question that starts looming large over the parent’s and the student’s mind right from class 9. More often than not, the decision of picking the choice of subjects to study in class 11 & 12 is taken by the parents, if not determined by your class 10 marks. But ideally, you should choose your subjects on the basis of your aptitude, personality, interests and career plans. How can students establish where exactly their aptitude lies? How can they determine and finalise which subjects match their aptitude and interests? Parents often don’t take their children seriously when it comes to making such decisions. And students end up giving in to parental pressure and choose subjects which lead to “lucrative” and “safe” career options.
