As the final exams approach, all the students are most likely busy with preparations, but have you studied for your practical exams as well? Though being an essential part of the CBSE Board final examinations, the practical exam is often overlooked and ignored. Most of us do not pay attention to details and procedure when teachers are demonstrating the practical experiments in class. But along with having the theoretical knowledge, practical education is also important to help you learn and understand the concepts in a better way that can be memorized for longer term. Practical examination is a test to determine if the student is able to implement theoretical knowledge into practical life.
Generally the practical examination pattern varies a bit subject wise but still there are some common practices that can give you an edge.
Below we provide you the 6 most important tips to follow that will help you to outdo others in the CBSE Class 10th and Class 12th Board Practical Exams:
1. Concept behind the specific experiment
Read the question carefully and thoroughly then only you can understand the principle working behind the particular experiment. If you know about the concept of each and every experiment conducted during the class, performing it is not at all a tough task.
2. Learn the procedure to conduct the experiment
Make a series of steps to conduct the specific experiment given to you. Different experiments have different procedures. So you should know how a particular experiment is to be carried out and what is the apparatus needed for that experiment.
For example, if you are asked to convert an ethane to ethanoic acid then different steps followed are:
- Conversion of ethane to chloro-ethane using chlorine gas in the presence of sunlight
- Chloro-ethane to ethanol with the help of aqueous KOH
- Then finally converting ethanol to ethanoic acid by treating it with alkaline potassium permanganate
3. Don't cram the readings
As different apparatus have different specifications so the set of readings obtained this time may be different than those taken during the class. It's better to clear your basics rather than cramming. Sometimes the various set of readings you obtained may be far different from each other which will not lead to an accurate average value. In this case you need to recheck your apparatus settings and rectify the error.
4. Be good with diagrams and circuits
Visualize and draw rough diagrams for the experiments to prepare. Particularly in physics, learn the circuit diagrams carefully and you must have a clear idea about how the different terminals are connected to each other. During the exam the examiner may come and reset all your apparatus settings just to check whether it was not preset and may ask you to reconstruct the whole setting. Thus to prevent casting the bad impression over the examiner you should be well prepared with diagrams and circuits.
5. Be confident during the practical examination
A student should be confident about whatever topic is given by the examiner. During the experiment, remain calm and document the entire procedure you follow so that you are able to answer oral questions asked by the examiner in the oral exam after practical is completed. Most of the times, the examiner asks the questions that relate to the topic associated with the experiment.
For example, you might be carrying out an experiment to calculate the focal length of convex mirror but when you appear for viva you may be asked questions related to concave mirror. But due to nervousness you may go blank and would be unable to answer the questions that were not really tough. Thus be confident to face the queries that may not be related to the particular experiment you are doing.
6. Sharpen your senses
While carrying the chemistry practicals you must have a fair idea about the smells and colours of different organic solvents. This will help you identify and distinguish different compounds used or firmed during the experiment easily.
Collaborated with sheer practice and continuous learning, these tips will surely help you to perform outstanding in your practical exams.
ALL THE BEST!!!
