Hi

NATA score is out of 200 and therefore from your information i calculated your merit score( assuming you got 85% or above) which is coming around 69. 106 in nata is an above average score not bad at all. If your board results are high enough 85% or more you can get good colleges like

Jadavpur University

Jj college of arch

Susant college of arch

Anna University

Rizvi college of arch

R.v college of arch

And much more

If less than 70% i suggest you reappear for nata.

In the last few years trend followed by cept is you need 80 merit score or more which means you need 140 + marks in nata to get admission in cept

You have got a good percentile in jee mains and your score should be around 100-110. As for your jee percentile there are good colleges like

Motilal nehru national university

Nit goa

Nit delhi

International Institute of information technology,  bhubaneswar

Nit rourkela
