Hello!

Mostly CBSE will give you information regarding examination before 3-4months. There might be confusion that is due to the pandemic situation. For practicals there will be reduction in syllabus or they will provide you with an alternative. They will definitely give you the required practice, some schools will even give the datas and ask the students to just replicate that. So don't worry about practicals.

ALL THE BEST. Hope the answer was helpful.

Thank You
