I have failed in physics, chemistry and biology in 2017 (CBSE Class 12 Board exam). I want to reappear in 2018 as a private candidate. Can I? Should I have to appear in practical exam? May I keep my practical marks?

Yes, definitely you can re appear for the examination in the next year as a private candidate, there is no problem in it.
Candidates those who have failed in some particular subjects under CBSE Board can apply for the compartment examination in the very next year of the examination. Since, you are going to re appear in the above mentioned subjects once again, you must have to appear in the practical papers also (if any).

Since, you have failed in more than one subject in your class 12th Board exam, so your are not eligible for CBSE compartment exam. You have to reappear for the class 12th board exam in the next year.
