Why NCERT Solutions Matter for Class 10 Science
The CBSE board exam for Class 10 Science is 80 marks (written) plus 20 marks internal assessment — totalling 100 marks. Almost every question in the written exam is either directly from NCERT exercises or is a slight variation of them.
Three reasons NCERT solutions are non-negotiable:
First, CBSE sets question papers strictly from the NCERT syllabus. Topics outside NCERT are never tested in boards. So studying NCERT thoroughly is the most efficient use of your preparation time.
Second, the marking scheme follows the NCERT answer structure. Writing answers in the format shown in NCERT solutions earns you full step marks. Deviating from this structure — even with a correct answer — can cost you marks.
Third, NCERT solutions build the conceptual foundation for competitive exams. Students planning to appear for JEE or NEET after Class 10 benefit from understanding Class 10 Science concepts deeply, not just memorising them. eSaral's solutions are written with this dual purpose in mind.
EXPERT TIP (eSaral Faculty, IIT Bombay): Many students read the NCERT chapter but skip the in-text questions and exercise questions. This is a mistake. In-text questions test chapter-level understanding, and exercise questions test application. Both types appear in the board exam. Solve every single question — not just the ones you find difficult.
