The CBSE Class 10 previous year question papers for science is divided into four sections which are A, B, C and D.
Section A: This section consists of objective types questions each of 1 mark. This section will have two questions and both the questions are to be answered.
Section B: This section will have a very short answer type questions which carries 2 marks. Three questions will be asked and all the questions are to be answered.
Section C: This section is for 30 marks and will have ten short answers and they carry 3 marks each.
Section D: This section is also for 30 marks and will have six long answer type questions and they carry 5 marks each.Section E: This section is also for 12 marks and will have six short answer type questions and they carry 2 marks each.
The best way to keep yourself prepared is to refer to the CBSE 2019 Science Question Paper with solutions. Referring to them have a raft of benefits which are as follows:
Questions Format & Model of the paper
Having a piece of sufficient knowledge about the type, nature and format of the questions being asked in the examination is really necessary. The questions can be in the form of subjective or objective. The strategy used to answer them will differ. Subjective answers take a longer time to write when compared to the objective type questions. But, objective type questions take a long time to think. The best and the only way to be prepared to tackle these hurdles is by referring and practising CBSE Board Exam 2019 Science Question Paper of Class 10
Having a thorough understanding of the exam pattern is necessary to develop an attitude towards clearing the exam. This will give you an extremity to play by your strength. It gives you a clear picture regarding the weightage on topics, marks allotted, and most importantly the important topics that would be targeted in the paper. It will help you formalize a strategy for your preparation making your groundwork stronger.
Point out Important Topics
CBSE Class 10 Science has a huge and vast syllabus to complete. They cover an array of topics with extremely detailed conceptual understanding. However, the exam does not need you to study all of them. A proper analysis of previous years paper will help you understand topics that are repetitive with a lot of weightage making your preparations smarter and easier.
An exam is a place where you have to reproduce all the information learnt by you for many months in mere hours. This is possible only with repetitive practice of Science Question Paper 2019 Class 10. Practising with CBSE Class 10 Science Paper 2019 Solutions will help you to train your mind to remember the right answers at the right time. This will help you to give your 100% in the exam hall without feeling any extra pressure. Remember “Practice makes a man perfect”.
Evaluate Your Preparation
Repeated practice of previous papers will help you to analyse your preparation. It will point out your strengths and weak spots. This will give you a better picture of topics that need more effort and areas that need only a quick revision. Accessing your preparation will also help you to excel in the competition outside. Repeated practice will make you well versed in all the topics of your syllabus.
Be Prepared Mentally
No matter how well you prepare, exams are a nightmare for most of them. Those three hours in the exam hall are the toughest and longest of the day. We sometimes even tend to forget answers and mix up questions in sheer fear. While practising, being able to answer right in the given frame of time will make you realize there is nothing really to be afraid of. It will fill you with confidence in making your performance in the exams better for best scoring.
Having to reproduce an entire year's syllabus in a few hours is a daunting task. It is demanding, pressuring but yet necessary. It is important to be able to allocate specific time to specific questions to be able to answer them perfectly. This will increase the quality of your preparation as well as your answer. Practising previous years question papers will help you to be prepared to allocate the necessary time for each question and allow you to give your best in the limited time constraint.
