B.Tech as you know well is a 4 year course. Polytechnic will be 3 year course only. After polytechnic if you want to do B.tech you'll be admitted directly to the 2nd year in most colleges.

So for a polytechnic person to be equivalent to his B.tech counterpart, one will need 3 years of polytechnic+ 3 years of B.tech.

What you can achieve in 4 years of B.tech will take 6 years through polytechnic. Also anywhere you'll go, an engineer will be senior to a diploma holder (polytechnic).

But in the end its completely up to you, so I suggest you take a more in depth look into both these courses, and then finally decide for yourself.

Feel free to ask if you have any more queries.

Hope this helps!

All the best!

Hello,
One can't compare Btech with Polytechnic. Btech is obviously more valuable and has higher placement opportunities based on the college and student's skills. Choose a course based on your interest only.
Good luck.

Hello student there's no comparison between B.tech and polytechnic boht are two different thing. You can pursue polytechnic after class 10 but you can pursue B.tech after +2 and if you want to take admission in best B.tech colleges like nit and IIT then you have to apply for jee main. On the basis of your rank and marks you'll secure your seat in respective colleges.
If you have doubt which is good or bad then both of it are good but it depends on your college and your academic performance that'll only help you to get a job in a good company.
Feel free to comment if you have any doubt
Good luck
