Hi Harsh!

No doubt the level of subjects in 11th class is much more difficult/higher than that of subjects of 10th class. Upto 10th class Physics, chemistry and biology were studied as only one subject. But from 11th class onwards they are recognized as different subjects are studied in-depth. If you have chosen science as your stream in 11th class, you must have had some interest in science. Earlier, you will find things difficult for you, but soon when you will give some efforts to understand the concepts then it will be become easierr for you. Give subjects/topics some time and study sincelery, you will be able to get the things.
