Multiple Highschool diplomas

I have multiple highschool diplomas. CBSE was one that I messed up due to a lod of problems at school and a general incompatibility with the curriculum. However I am sure of acing the A levels with a more competitive set of subjects. Should I withhold my CBSE scores considering that I took the A levels without a school?

No, you’ll need to submit the CBSE scores as well as any class IX or X scores, IGCSE’s, etc. Plus the A Level scores 3-4A levels or 2 AS 3different A2).
