Hi

Any school which is affiliated to CBSE is called CBSE recognised/certified.

Now,

Both Private and government schools can be  affiliated to cbse and thus can be cbse certified.

For example,

Kendriya Vidyalayas are government chain of schools  which are affiliated to cbse while DAVs are private chain of schools affiliated to cbse and thus certified by CBSE.

So,

If your private school is affiliated to CBSE and you have chosen CBSE certified while filling the form then you have done it right, and thus there's nothing to worry at all.

Now very limited time is there for jee main 2022 so to prepare well

• Revise the concepts

• practice  chapterwise important mcqs/ questions which you you would have marked for revision during your preparation.

• go through mock test papers as it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination.
