Good to hear that you're interested in medicine, you must already know that it's a tough way ahead. Since you are still only in Grade 9, the first step I would suggest is to focus on your studies in school and do well (especially in physics, chemistry and biology). Building a strong foundation of knowledge is essential for NEET (if you want to study medicine in India). That way it'll be easier for you to grasp concepts during your NEET prep later on. Doing well in Grade 10 is also important.
It's too early for you to start studying for NEET as the syllabus is mostly Grade 11 and 12 portion, which you won't understand just yet. You can start looking for a good coaching institute to join when you go into Grade 11. Choose one that is preferrably close by so you don't have to spend time traveling and it should have a good reputation.
You can also watch NEET topper interviews and read articles about how they studied, which books they used and other tips and advice from those who did well. It will give you an idea in advance about the do's and don'ts of NEET prep so that you won't be lost when you start.
Overall, just study hard in school and keep your goal in mind. Stay proactive, good luck!
