CBSE

No, I shall be answering you for the subject of chemistry. Actually, Class 12th Chemistry is far easier than the one you have in 11th. If you SEE Physical Chemistry in class 12th is pretty easy compared to class 11th as here questions are directly based on the formula. If you target boards, then I would recommend you to please have a piece of good knowledge of how to use the mole concept, as it is the base for calculations in Physical chemistry. Now for organic, it is only a perception that is drilled down into your brains by the people around you that it is difficult; Trust me, there is nothing easier and beautiful than organic in class 12. Each reaction, mechanism etc. Repeats after chapter after chapter. Only in inorganic, P block is a chapter which may test your limits of memory, but you can do it. Please, Take this note. DO NOT SKIP CHEMICAL BONDING AND MOLECULAR STRUCTURE CHAPTER IN CLASS 11, IT IS REALLY IMPORTANT FOR HAVING A CLEAR UNDERSTANDING OF ORGANIC AND INORGANIC CHEMISTRY. IF YOU ARE IN CLASS 12 AND ARE FACING DIFFICULTY IN INORGANIC & ORGANIC, make it a point to go back and study that chapter from word to topic, as it helps you to get a crystal clear understanding of class 12 organic and inorganic. Nevertheless, Constant revision and solving a lot of problems will really boost your confidence and prepare you well for your boards. Make it a point to solve minimum of 10 years' of papers before giving your boards. My wishes with you man.
