CBSE 12th Physics Practical Question Papers 2025: Preparation Tips

The model question papers will help students with CBSE 12th preparation. Students are advised to follow the below-mentioned tips while preparing for the Chemistry practical exam.

• Practising the experiments

It is important to keep practising the experiments because there are several minute details to be taken care of while performing the experiments. Practising on a regular basis will only enhance the speed and accuracy of the results of the experiment.

• Understanding the experiment

The experiments must be understood clearly before practising. The procedures must be understood well.

• Practical Record Book

All the experiments must be noted down well in the practical record book. The procedures, observations and inferences must be written in a step-by-step manner.

• Viva Voce

The viva voce will be conducted on the basis of the experiments performed. Therefore it is important to know the concepts thoroughly.

• Investigatory project

The topic selection for the investigatory project must be done carefully. The observations must be charted down.

• Revision

It is very important to know and remember the topics very well. Therefore revising the topics on a regular basis is very helpful.

• Managing time

Time management skills must be honed. It is important to set the time that can be dedicated to each experiment before starting with the same.
