The weightage of 11th and 12th in JEE, IIT, and NEET varies from exam to exam. In general, both 11th and 12th standard syllabi are important for these exams.
For JEE and IIT exams, the weightage of 11th and 12th is approximately equal. However, the difficulty level of questions may vary. In JEE, more weightage is given to topics like calculus, algebra, and trigonometry, which are covered in both the 11th and 12th standards. On the other hand, some topics like electromagnetic waves and communication systems are covered only in the 12th standard but have a lower weightage in the exam.
For NEET, the weightage of 11th and 12th is also almost equal. However, some topics like genetics, molecular biology, and ecology are covered more in the 12th standard than in the 11th standard.
It is important to note that a good understanding of both 11th and 12th-standard topics is essential to score well in these exams. Students should focus on mastering the basics and concepts before moving on to more complex topics. Additionally, regular practice and solving mock tests can help students identify their weaknesses and strengths and prepare accordingly.
