Why Do Students Neglect These JEE Main Chemistry Chapters

The following are some of the reasons why students neglect these chapters:
1. Students usually adhere to "top chapter" lists and forget about the rest of the syllabus.
2. Memory-based subjects are usually done close to the end of the period.
3. Students may feel that easy topics will carry less weight in the exam.
4. Certain chapters are less significant since they comprise fewer numerical problems.
5. Sometimes, students concentrate only on the chapters that come in one specific shift.
