How to prepare and score Good marks in Chemistry Paper?

The most important period in a student’s life is class 11. There are many competitive examinations ahead, which you will be appearing for. You also have class 12 board examinations the very next year. Certainly, it is important for every aspiring student like you, to have an excellent command of the subjects taught in class 11. This is very essential for your boards, as well as competitive exams like JEE and NEET. The syllabus of class 11 is the fundamental part of any competition, including boards.

Chemistry is one of the most important subjects from a competitive point of view. If you see the standard of questions asked in boards in competitive exams like JEE and NEET, you will figure that this subject can be very scoring. The kind of questions asked from chemistry fetches you easy marks with not much effort. You just need to know the concept well and you’ll be able to solve any question asked. Chemistry has its applications in various different fields. So it becomes all the more important to study the subject well, for students aspiring to have a career in science. You might be thinking about how hard it is to get a decent score in the subject. To this, the answer is that it is not a difficult thing to get a 100 in boards. All you need is, to remain focused and keep yourself motivated throughout the journey of your preparation. You know the popular phrase, ‘Practice makes a man perfect’. It is your consistent practice and hard work that will help you gain a strong command of the subject.

Here are a few tips that might help 

Prepare a good timetable – There will certainly be some chapters that you don’t find boring or difficult to study. You might feel demotivated after studying these chapters. But omitting every such chapter is not an option. Every chapter is important from the exam point of view. You should prepare your time table in a way that you give extra time to the tougher chapters. Try to complete the difficult part of the syllabus first. Once, you have completed the harder portion, you can now study the easier chapters. This will make your preparation strong.

Know the exam pattern and syllabus – You should be very well aware of the pattern of your board exam. This will help you strategize your exam preparation easily.

Focus on the important topics – You should focus on every topic in the syllabus, as questions are asked from each section.
