Hello ,
As your query is you want to take admission in both ITI and Polytechnic together. ITI is the course of 2 years and Polytechnic for 3 years and both of them require effort and time as well. Yes you can complete both the course together and can apply for them at the same time but in my opinion it will be a better choice to go with one course at a time only because both of them required time effort and study so if you will go with them together that might make pressure for you but at the end it's all about your call whether you can take both of the courses together or not but yes according to set a norms definitely you can go with both the courses together at the same time.
Further, if you need any other detail regarding the same you can let me know in the comments section below and I can help you with that.
I hope your query is solved.
Thank you.
