hi,

see you can not join b.Tech course after completing ITI training. you can get admission in b.tech course after completing three years diploma course in relevant stream, diploma pass students can join b.tech as lateral entry in second year of b.tech course  by clearing  state wise lateral entry exam test. for example JELET, bihar lateral entry test etc.

you should join the diploma engineering course after completing 12th, it would have saved your years , since currently you are doing ITI program you are eligible to apply for diploma course at the second year of diploma as lateral entry. then after completing diploma you may apply for b.tech course.
