CBSE Class 10 Science Exam: How to Score 100/100?

As the years pass, the number of students scoring 100 on 100 in science is increasing. It is no longer a feat accomplished only by star students as more and more students are learning the correct technique of studying and scoring in these board exams. Let’s see how exactly one can get a full score on a science paper.

Study the syllabus

While preparing for the CBSE board exams, it is so important for the students to know exactly what forms a part of the syllabus. This is usually outlined very well on the official website. Make sure the entire bulk of it is covered end to end again after completing it in school. This gives a sense of confidence with the portions and also acts as a revision.

Look at the weightage

Not all chapters carry the same importance when it comes to examination point of view. Focus on each topic based on the weightage of marks they carry. For example, chemical substance- nature and behaviour carries a huge chunk of marks and one can expect both short and long answer questions from this section. Focus more on this and try to cover all segments from here. When it comes to units like natural resources, try to study the most important aspects first. There is not much probability that a long answer question is given from this segment.

Analyse the question paper format

CBSE board examinations follow a strict question paper format which they mention well ahead of the examination. This format mentions the number of questions in each type and how many marks they carry. For example, the greatest number of marks fall in the “understanding” type of questions, out of which there are two long answer questions, two short answer questions and four objective questions. The “creating” type of questions only form a total of nine marks, all of which fall into the short answer questions. Knowing this will help in eliminating learning bulks of information that might not even be asked in the examination.

Take internal assessment marks seriously

There is a small segment that carries about 20 marks specifically for internal assessment. This would include class tests, quizzes, practical and lab work and portfolio. Since this happens throughout the year, it is very easy to not take them seriously. Make sure you do not lose any marks in these segments as they also add up to the final score.

Preparation for physics

When it comes to physics, it is either the most hated or most loved amongst the three. 

Firstly, be thorough with the NCERT textbooks. Many times, the MCQ section would contain questions that are directly taken from the textbook. Read every line thoroughly and make sure that it is retained. Reading the textbook more than once would also be of great use.

Make your concepts very clear. As and when a topic is completed in school, go back and read through it so that any misconceptions can be cleared immediately. The concepts learnt at this stage not only help in scoring but can also help you answer any type of questions in the examination. 

Practice numerical problems. This one goes without saying that numerical questions can either be a big bonus in the exam or end up becoming a weakness. Practice makes you perfect and the concepts that were learnt earlier will come into use here. Look through the solved examples for better clarity.

Make systematic notes. After completing a chapter, try to make notes of what you find is important from it. This would come in handy during revision. There are many institutes providing CBSE class 10 science notes pdf with easy-to-understand points and summaries.

Preparation for chemistry

Practice the equations. One of the most important parts of chemistry is the equations. While the basic skeleton can be learnt by understanding, the complete equation has many elements, including balancing, all of which carry separate marks. Memorizing them will definitely save time in the exam hall.

List of formulae. There are many chemical compounds whose formulae have to be memorized. Make a list of all of them and keep looking into them from time to time so that it doesn’t become a separate task in the end.

Do not ignore the theory. Chemistry contains a good number of numerical problems, equations, reactions but it also has a bit of theory which we may not pay attention to. Although very few questions form this part, it still plays a role in scoring that 100.

Preparation for biology

Prepare notes. This is especially important for biology. The subject is theory-based and has many terms to get familiar with. The NCERT textbook is not written in an organised manner and having notes will greatly help while learning.

Practice the diagrams. There are diagrams given in the NCERT and the teachers would also make you draw separate diagrams which might be easier. Learn and practice them with proper labelling. These will fetch plenty of marks, especially if done neatly.

Memorize terms and definitions. There are many tables, definitions, names and new terms which are all mentioned in the NCERT textbook. Make a separate note of them and keep looking at them from time to time.

Application-based questions. Even biology has a few practical questions which can be better understood by reading the laboratory manual section. Many one or two-marker questions are asked from this part of the book.

Stay confident.

Half the battle is won when you believe that you can do it. Do not overwhelm yourself by looking at the entire syllabus as one big portion but start small and keep looking forward. With regular practice, anything is possible. 

So, these are some of the best tips followed by most toppers to score their perfect 100 in the science paper. Go ahead and get working to bring that 100/100 home!
