The marks division for each unit of both theory and the practical segment will enable students to understand which topics carry the most weightage in the examination and prepare accordingly. Apart from CBSE 12th chemistry syllabus, you can access the syllabus for other subjects like biology, physics, mathematics etc. by visiting the official website of Central Board of Secondary Education.

  1. Prepare a Routine –

Once you know the whole syllabus, you can start framing a daily study routine or plan. It will enable you to effectively manage your time between preparing for chemistry and other subjects for class 12 board examinations. Furthermore, with a study plan, you can devote equal study time for each of the topics from CBSE 12th chemistry syllabus. In addition to studying, you should also set aside time for revision and mock tests in your daily study routine along with short breaks.

The theory paper will be separated into three segments – long answer questions, short answer questions, very short answer questions. 

Long answer type section will have three questions of 5 marks. It will also have nine short answer types questions of 3 marks each as well as ten short answer types of 2 marks each. Lastly, the question paper will also have eight very short answer type questions of one mark each.

Furthermore, there will also be internal choices for five questions from each of the sections in the overall question paper.

Apart from class 12 examination, CBSE 12th chemistry book also comes in handy while preparing for competitive examinations like JEE, NEET etc.

However, you can refer to reference books from other publications that follow the same curriculum and class 12 chemistry solutions by experienced teachers to learn in details about any particular topic or concept. 

  1. Sit for Regular Mock Tests – 

It is one of the most effective ways to practise and test one’s progress before a major exam like CBSE 12th chemistry board examination. Answering sample question papers or previous year’ papers will give you an idea of the question paper format and understand your level of preparation. Remember that the duration of theory examinations for class 12 boards are for three hours. You must practise completing the whole paper within the given time

Regular mock tests will enable you to acclimatise with the actual test environment, improve your speed and level of performance. Performing well in the mock tests will boost one’s self-confidence and reduce pre-exam nervousness to some extent.

Going through sample CBSE 12th chemistry paper will also help you to revise the syllabus repeatedly so that you retain all the information on the day of the actual examination. It is especially true for chemistry which contains a considerable number of formulae and numerical problems in each chapter. 

  1. Do Not Forget to Take Breaks – 

One should avoid studying for too long at a stretch since it can have negative effects. It will make you feel mentally exhausted, which will prevent you from learning anything. Hence you should focus on quality studying instead of quantity and remember to take short breaks after every few hours to prevent yourself from getting too overwhelmed. It will help your mind to relax, and you will be better able to focus on your studying after your break. You can also set timers on your phone to remind yourself to take a break.

  1. Get Enough Sleep and Eat Healthily – 

You should also pay attention to your physical health while studying for your CBSE 12th chemistry examinations. Preparing for board examinations can feel overwhelming, but you should not neglect eating and sleeping as it can have adverse effects.

Additionally, Lack of proper sleep will also leave you feeling exhausted, which will interfere with your ability to concentrate and retain information. Therefore, make sure to eat nutritious meals and get enough sleep every day. Short naps in between studies also enable one to focus easily and grasp difficult topics quickly.

  1. Learn to Relax – 

Preparing for a major examination like CBSE 12th chemistry boards can be quite stressful. That is why you must learn to relax and manage your stress, so it does not interfere with your exam preparation and revision. 

You can try to meditate for a few minutes every day, which will reduce your stress and enable you to stay calm and focused. Apart from that, stretching and exercising will also help you to relax, as well as stay fit.
