Hello, Aspirant!

First of all the question you have posted is a bit confusing. But let me try to answer your query.

For Central University Entrance Exam (CUET), one can add upto six domain subjects. Since you've already selected four subjects, you can add two more subjects of your choice.

You have also mentioned DU in your question. In that regard if you want to pursue B.El.Ed course in Delhi University, then this year there is DUET. You can select upto four subjects for this entrance test. While in some colleges, the admission will be merit based.

Hope this answers your query. Do let me know if you require any further information.

Good luck.
