Y not? You can do.
You state norms for NIOS course is the way for Engineering after ITI.
Otherwise, you can join Diploma then Engineering in related courses. BTECH after ITI (https://www.iti50.com/p/after-iti.html)
Dear Gurpreet,
You cannot take an admission for B.Tech after completing ITI. For that you need to do a diploma in engineering in the stream of your choice.After completing your diploma program you are eligeble to appear for JEE main. You have a possibility of securing a seat in either of the IITs or any good state engineering colleges for going ahead with B.Tech in the respective stream of your choice.
Hope this helps
Good luck!
