Hello Sir. The above link you suggested is for 2019. And Thanks for your quick response.
Even I have come through the similar answer regarding this but I was confused after seeing this point in CBSE Notice for Private Candidates appearing in 2020 exam. The point was,

4. Candidate will have to appear for the practical examination irrespective of the fact whether he/she has passed in the previous examination. (Page 8)

Requesting a clarification on this and what they meant here

Murali PT Hey there
2020 CBSE compartment link will be on our website soon. In the official CBSE notice it has nowhere written that taking practicals is compulsory for compartment students. But
I am giving you link of CBSE official notice link for 2020 please be sure and even if doubt persists ask in comments.
