when i will start the preparation for MBBS or JEE?? now my daughter is in 6th class .

Ans: It's not that they should start from class 6 or 7. Preparing for NEET/JEE shouldn't be taken so seriously that it reflects on the children as some monstrous thing.
As parents we can do this,
1. Don't let them know that they are preparing for some exam.
2. Give them the subjects in such a way that they understand the concepts and develop capability to apply the knowledge to solve problems.
Start these two activities as early as possible, maybe from standard 6.
By the time they complete their 10th they would have realised the importance of subjects indigenously.
And that's where you can start feeding him with the different crucial materials required for NEET/JEE.

Ans: Jayashri, here is a detailed and practical guide to help you prepare smartly for JEE and other engineering entrance exams starting from 9th grade, aiming for top scores in 2029.

Start Early and Build Strong Basics:
Before your school or coaching teaches a chapter, watch chapter-wise videos from reputed coaching centers on YouTube, focusing on NCERT-based content for Physics, Chemistry, and Math. This early exposure helps you grasp concepts better. As you study, immediately note down any doubts or difficult points. Don’t leave them unresolved—use Google, ask your teachers, or clarify during coaching sessions.

Organize Your Study Material:
Maintain a separate notebook for complicated or lengthy concepts. Regularly revise these notes to strengthen your understanding. Similarly, keep track of questions you answer incorrectly in practice tests or mock exams. Revisiting these repeatedly will help you avoid repeating mistakes.

Practice Previous Years’ Questions:
After completing 10th grade, start solving JEE previous years’ questions chapter-wise. Once you finish a chapter in 11th or 12th grade, immediately attempt related past questions. This builds familiarity with exam patterns and question types.

Use Time-bound Online Tests:
Ensure your coaching provides chapter-wise and full syllabus online test series with detailed solutions. If not, enroll in one or two online test series from reputed coaching centers. Regular timed tests improve speed, accuracy, and exam temperament.

Effective Study Routine:
At home, study in focused intervals of 35-40 minutes followed by 5-10 minute breaks. Identify your most productive hours—early morning or late evening—and schedule your toughest subjects then.

Focus on Maths and Core Concepts:
In most engineering exams, rank depends heavily on Maths scores, followed by Physics and Chemistry. Strengthen your Maths skills through regular practice. For Physics, use books like HC Verma and Irodov to build deep understanding. For Chemistry, NCERT remains the foundation.

Create a Study Plan and Revise Regularly:
Make a realistic timetable covering all subjects and stick to it. Allocate more time to weaker topics but don’t neglect others. Revise frequently using short notes or flashcards. Solve mock tests and previous year papers under timed conditions to simulate exam scenarios.

Stay Healthy and Motivated:
Maintain good sleep, nutrition, and exercise habits to keep your mind sharp. Avoid distractions like social media during study hours. Stay positive and confident—consistent effort over time yields great results.

Summary
Begin your JEE preparation early by understanding chapters through NCERT-based videos before formal teaching. Note and clear doubts promptly. Maintain separate notebooks for tough concepts and wrongly answered questions, revising them regularly. After 10th grade, practice previous years’ questions chapter-wise. Enroll in time-bound online test series to build speed and accuracy. Study in focused intervals during your most productive hours. Prioritize Maths, followed by Physics and Chemistry, using recommended books. Follow a structured study plan with regular revision and mock tests. Stay healthy, avoid distractions, and keep motivated. With dedication and smart strategies, you can confidently aim for top ranks in JEE and engineering entrance exams in 2029. All the best!
