Hello

There is no internal marking as happed in class 12th CBSE.

You have your theory paper and practicals (which are taken by some external examiner who visits your school).

From 2019–20 CBSE introduced internal marking for some subjects like english and maths but there are some rumours that this could be changed for 2020–21 batch and these internal marks will also be given by some external examiner who'll visit your school to take the practical. But you've to wait for the CBSEs official syllabus and statement which is likely to be released in may (not confirmed due to covid-19).

Hope it helps you

Thank you
