Hi,
CBSE allows a c andidate having 6 subjects and got compartment in two subjects can appear in any one of the two compartmental subjects. Students who have 6 subjects and declared PASS but could not clear one subject, can appear as an Improvement category in July 2019. Now as you want to take up your exam in 2020, and you opted 5 subjects. Then according to eligibility criteria, you can take up at most two subjects for improvement.
I wish you all the best,
Thank you
