The Joint Entrance Examination (JEE) Advanced is a national-level examination conducted by the National Testing Agency (NTA) for admission to Bachelor of Technology (B.Tech) and Bachelor of Engineering (B.E.) courses in Indian Institutes of Technology (IITs), Indian Institute of Science Education and Research (IISERs), Indian Institute of Science (IISc), and other participating National Institutes of Technology (NITs).
JEE Advanced is the second stage of the JEE examination, following JEE Main. The examination is conducted in online mode and consists of two papers: Paper 1 and Paper 2. Paper 1 is divided into three sections: Physics, Chemistry, and Mathematics, while Paper 2 is a compulsory aptitude test.

According to research and after hearing from students, they found the overall level of Paper-1 Moderate to Difficult level but not easy. They also have reported Maths was Easy to Moderate, Chemistry was Moderate, but Physics was relatively difficult. Chemistry was not balanced as more weightage was given to Organic Chemistry.
And they have rated Paper 2 as moderate. According to them Maths was difficult, Chemistry was moderate and Physics was Moderate to Difficult.

Preparing for JEE Advanced requires a strategic approach, a clear plan, and a lot of dedication. Here are some preparation tips to help you crack the exam:

Step 1: Start Early-:

The very first step is earlier you start preparing, the better. Give yourself at least 12-18 months to prepare for the exam. This will give you enough time to cover the entire syllabus, practice consistently, and develop a strong foundation in each subject.

Step 2: Understand the Syllabus-:

Familiarize yourself with the JEE Advanced syllabus and make sure you understand what topics are being tested. Focus on the important topics and concepts, and make sure you can apply them to solve problems.

Step 3: Create a Study Plan-:

Create a study plan that covers all the topics and subjects. Break down your study material into manageable chunks, and allocate time for each topic. Make sure you leave some buffer time for revision and practice.

Step 4: Focus on Fundamentals-:

JEE Advanced tests your understanding of fundamental concepts, so make sure you have a strong grasp of the basics. Review your class notes, textbooks, and online resources to fill any gaps in your understanding.

Step 5: Practice Consistently-:

Practice is key to improving your problem-solving skills. Set aside time each day to practice solving problems, and gradually increase the difficulty level as you progress.

Step 6: Focus on Weaknesses-:

Identify your weaknesses and focus on improving them. Make a list of topics or concepts that you struggle with, and spend more time practicing those areas.

Step 7: Use Online Resources-:

There are many online resources available to help you prepare for JEE Advanced, including video lectures, online courses, and practice tests. Utilize these resources to supplement your studies.

Step 8: Join a Coaching Class-:

Joining a coaching class can be beneficial if you need additional guidance and support. Look for a reputable coaching class with experienced teachers who can provide personalized attention.

Step 9: Take Mock Tests-:

Take mock tests to simulate the actual exam experience and identify areas where you need to improve. Analyze your performance, and work on improving your weaknesses.

Step 10: Stay Motivated-:

Preparing for JEE Advanced can be challenging, but it's essential to stay motivated. Set small goals for yourself, reward yourself when you achieve them, and remind yourself why you're working towards this goal.

Step 11: Manage Your Time Effectively-:

Time management is crucial when it comes to JEE Advanced preparation. Make sure you allocate your time effectively, and prioritize your tasks accordingly.

Step 12: Stay Healthy-:

Don't forget to take care of your physical and mental health while preparing for JEE Advanced. Make sure you get enough sleep, exercise regularly, and eat a balanced diet.

Step 13: Review Regularly-:

Review what you've learned regularly to reinforce your understanding of the concepts. Go back to your notes, textbooks, and online resources to refresh your memory.

Step 14: Focus on Application-Based Problems-:

JEE Advanced tests your ability to apply theoretical concepts to solve problems. Practice applying theoretical concepts to solve problems, and try to solve different types of problems.

Step 15: Don't Overstress-:

Finally, don't overstress yourself while preparing for JEE Advanced. Take breaks, relax, and don't compare yourself to others. Stay focused on your goals, and believe in yourself
