JEE Mains & Advanced

Chemistry is one of the three subjects of Science that is first introduced  in class 6 to students and then it continues to be as a main subject till class 10th.after that is students choose PCM in their class 12th then chemistry will be main subjects in class 11th and class 12th. Some students find Chemistry easier than other subjects like Biology, Physics or Maths with respect to their streams. However, on the other side some students also find it more difficult to score in Chemistry than in the others.

Class 11 is an important stage in the higher education of any student. It is the time where you are introduced to the concept of streams with different subject combinations that you need to choose from. This decision may bring a massive impact on your future career options. It is also important for you to score well in Class 11. All the subjects taught in Class 11 introduce to students a number of new topics while some older topics are taken to the next level of difficulty.

Chemistry in Class 11 brings a wide variety of newly introduced topics that you have not read in the previous classes. All of these topics are important to help build a strong base in the subject for higher education in colleges, especially for the students who are planning to build a career in Chemistry.
