Hello,

If you have the proper certificate of 10th and 12th including your marksheet then you can absolutely use them. Generally gaps are not asked in any of the colleges through NEET.

But some of the private colleges or the Universities/colleges which comes under State University may have to make affidavit for the gap period but that's rare and you need not worry much about that.

Apart from these , the basic eligiblity criteria for NEET are as follows -

1. Candidates must have passed their 12th with Physics, chemistry and Biology/Biotechnology as compulsory subjects with atleast 45% for general and 40% for sc/st.
2. There is no upper age limit criteria for it.
