Standard 12th is the turning point in the life of every student who aspires to achieve something in his life. His devotion to work and a healthy foundation is the basis which can pave his road to success. After being a matriculation pass, every student has to decide what he has to choose for his life, which will prove to be the best for his nearing future. Some may want a stream because of passion or to follow their dreams; some maybe because of family pressure for a particular direction and imitating their peers.

Whatever happens, whether it's out of interest or imposition, one has to pursue the best from it because it is the deciding factor for the future waiting for our arrival. We need to make our subjects strong so that we don't regret later that a little bit of extra effort might have proven useful.

In this article, I will be putting light on the subject, which is an integral part for any science student who wants to pursue Engineering or Medical. The course loved by many, the one with the play of the constituents used in our day to day life, which deals with our surroundings and the reactions which take place and that subject that is Chemistry. We are surrounded by this subject since birth but become aware from the very beginning of our secondary school life and continues till ages.

Chemistry of standard 12th is developed based on the foundation standard in class 11th. Standard 12 Chemistry is quite the core for the students who are planning to pursue Engineering.

To achieve success in any exam related to any science field related to Engineering or Medical, NCERT 12th Chemistry plays a vital role. All the concepts frequently asked in competitive exams are thoroughly covered. The topics are explained elegantly with simple steps and innovative approaches.

This book is written by content experts on the standard 12th Chemistry CBSE syllabus. Most of the boards recommend NCERT as a religious book for their studies. They are helpful to candidates who aspire to score good and easily crack competitive exams.

The way of presenting the content is quite beautiful as it is quite a student-friendly. The contents start from the very basics and go till the most difficult.

All the chapters are well covered, and the student can thoroughly revise all the above topics quickly. They include real-life examples and questions which help us to build our mind and shape it accordingly.

Students must deeply go though all the subtopics mentioned above as these are not only helpful for scoring in boards but also in competitive exams like JEE.

There is one supplementary book with NCERT 12th Chemistry that is Chemistry exemplar. This is an excellent book that has Multiple Choice Questions (MCQ) and subjective ones too. These two books are the one which paves your way for a glorious success.
