You may have doubts about the practical exams of class 12 because some of us were unable to score in the in-class 12 pre-boards 2019-20, and we start worrying about class 12 practicals.

Questions like; I haven't scored well in pre-boards will I get full marks in class 12 practicals or not?

All these questions will be answered in this post by the SchoolOkay. If you are a student and reading this post, just let me know in the comments.

You will feel glad that minimum marks are given in practicals in 27 out of 30, in any school and boards. This is because class 12 practicals are only conducted to boost your morale and check your practical knowledge, even in some schools practicals are not conducted properly.

I was also overthinking about my practicals, but they just went smoothly. This is only because every school wants good results, so just chill, don't bother too much about it. Your teacher will tell you how you need to do Class 12 practical physics, class 12 biology functional, chemistry class 12 practical, etc.

The Class 12 practical exam includes many things. Do they take place in a series? As far as my concern, it contains observations, readings, calculations, and how you perform that particular experiment.

After that, you have to make some observations and take notes of them. The teacher asks if you really did that experiment or not? If you have done it, then you must have proper details about it; otherwise, you will not get full marks if external put some questions about your experiment.


It doesn't matter which practical exam of class 12 you are appearing for physics, biology, chemistry, or any other according to your chosen subjects and stream. All written in the same way.

Some basic Q & A

What happens if I fail in class 12 Pre-boards? Will I get full marks in class 12 practicals, physics, chemistry, and others?

Of course, you can get full marks even if you fail your pre-boards. Pre-boards do not matter at all. The problem is that your teachers make your opinions based on your pre-board scores, so it simply means that if you have low scores on pre-boards, they are going to think that you are a weak student.

They are going to throw you into extra classes. So you need to make sure to get good passing scores in your pre-board exams so that your teacher does not think that you are lame student.
