Hi

Yes, Practical Examination will not be conducted again , the same marks of your Practical Examination will gets carried over, you will have to provide your marks details while filling the form as a private candidate  and you need to give only theory examination.

You can check the same on the official website of CBSE the link for which is provided below

Your profile suggests that you are a medicine experience so I am guessing that you are going to appear for either physics chemistry or Biology as private candidate.

Follow the below tips for your  examination

*in case you are going to appear for biology, you should read the chapter first then understand the biological processes and then learn them my heart and also learn the important examples. You can refer to books like trueman's Biology to understand difficult topics.

*in case you are going to appear for chemistry go through all the solved examples and intext and exercise questions of NCERT or your state board text book , in organic chemistry focus more on name reactions there are two questions from name reaction each year in board examination and many questions are based on them directly

*in case you are going to appear for physics, you can follow reference books like  SL Arora,  derivations are very often asked in your board exam ,so practice  all the derivations and do revise them as there are chances of forgetting them ,  go through solved examples and then go for unsolved numericals.

*Go through previous 10 year 12th cbse examination question papers as concepts are often repeated in exam so it will be of great help in your preparation

*Once you are done with your complete examination syllabus go through at least 3-5 mock test papers in each subject

Thank you
