Hi Deepak,

I am sure your teachers and guides will help you throughout the year to focus on your goals. But, as a student, I would like to advise you a few things before starting your preparation. 

• Start off with the fundamental topics that will build your base for further preparation. Most students start studying tough topics before their basics are clear. 
• Plan a total curriculum for the year, for example, allot what subject, what topic are you going to study in which month for the year. Seek guidance from your teacher while planning. Do not plan alone. Planning is the key.
• Always appear for as many tests as you can. Since you are a dropper, you have an idea of the subjects and there is no reason to skip tests just because you haven't completely done the topic.
• Don't take too much stress while preparing. There are a lot of options even if you do not get a good medical college.  

All the best for the future.
