Practical examination pattern varies a bit subjectwise and a lot also depend upon the External invigilator ( Generally They are good and cooperative in nature) . Subjectwise here are some of the important points that can give you an edge. Do keep in mind that practical has to be dealt with you and external examiner. Both of you don't know each other.

CBSE Class 12 Board practicals are very important. Getting full marks in practicals is very important but the dedication you need to give for them should be limited. The preparation for practicals should not affect your board marks. In most of the institutions the teachers try to give full marks to the students.

We are not saying you take board practicals lightly but learning how, why,  to do the experiments is sufficient for the practicals. For learning you can learn with ybstudy from the net and memoriae the formulas of them and even if you forget anything your teachers are always there to help you. So approach the exam with a cool mind. You can ace it very easily. All the best for your boards.
