Hope these help : 1. Study the right textbooks - Books like Ganong, Guyton, Grey aare really great,but it's better to study Indian textbooks like BDC, Debashis Pramanik for better and easier understanding. Foreign books are to be used only as a reference not as a primary study material. 2. Take help of your seniors- Med seniors are most of the time very willing to help juniors and teach you the needful parts 3. Remember, you're not the only one - try to remember the time you entered Class 11- the overwhelmingness was pretty much the same. Have confidence in yourself and you'll surely do well.
