"Mathematics can be a challenging subject for students and they have had a very weird love-hate kind of relationship with the subject. For some students, Mathematics is a very high scoring subject and for some, it is a trouble. The subject goes through a transition in Class 9 and introduces students to many new complex concepts and topics that can be tough for the students to understand initially. The complex concepts of the subjects can intimidate the student and they might feel underconfident regarding the subject. Its is very important for the students to have a thorough knowledge to score good marks in the exams.

The NCERT textbooks for Mathematics is the primary source of learning for the students. The students can practise the questions and prepare for the exams. However, the textbooks are not sufficient for the students to ensure a good result in the exam or to have a deep and clear understanding of the subject. Some concepts in the textbook can be briefly or vaguely explained and this can prevent the students from having a clear understanding of the subject. Learning beyond the textbook can help the students of Class 9 to have an optimum learning experience.

Secondary learning options can be very beneficial for the students but having a good source of secondary learning is very important. The students join multiple coaching classes and tuition centres to ensure a good understanding of the subject and think that these steps will them comprehend all the topics and concepts better but at the same time students end up losing out on a lot of their crucial study time while going from one coaching centre to another. This hectic schedule leaves the students with no time to study the subject by themselves and indulge in self-study.
