CBSE Class 10 Science Practical Exam 2020: Syllabus and Preparation Tips here
CBSE Class 10, 12 Board Examination 2020 will start from 15 February onwards. However, board is yet to release the complete timetable. But, before that schedule for CBSE practical examinations has been announced officially by the board. CBSE Class 10 and Class 12 practical examinations will be conducted by respective schools between 1st January, 2020 and 7th February, 2020.
At this time, when most of the students would be busy with wrapping up their syllabus and board exam preparations, hardly they would have bothered to prepare for the practical exams. Though being an essential part of the CBSE Board Exams, the practical exam is often overlooked and ignored. Most of the students forget the fact that the marks obtained in practical exams will be added to their scores obtained in theory papers for the final assessment.
Viewing the importance of practical exams, jagranjosh brings here the latest syllabus for the CBSE Class 10 Science Practical Exam along with some important preparation tips to perform well in the exam.

Preparation Tips for Class 10 Science Practical Exam 2020
- Read each experiment carefully to understand the principle working behind it which will help you to identify the category of that experiment for which you have a particular procedure to be followed.
For example, if you are asked to trace the path of a ray of light passing through a rectangular glass slab, then you should know the law working behind reflection, refraction and emergence of light to obtain the correct path of ray of light.
- Learn the step-wise procedure to conduct each experiment properly.
- Never try to cram the readings because different apparatus have different specifications which may cause an alteration in the readings obtained for an experiment at different times.
- Learn the circuits and diagrams properly, especially for physics and biology experiments.
- For chemistry practical, you must be good at distinguishing between various compounds and salts by their colour, odour or texture.
For example, you should be able to sense the rotten egg kind of smell of hydrogen gas which is colourless to observe.
