Hello Aspirant,


Ploytechnic or diploma is considered on of the best courses. And it certainly helps you in engineering.Polytechnic is a 3 year course choosed by students after 10th.
Diploma students can join to 2nd year of engineering degree course. So, the competition level for a diploma to a degree is less than 12th to B.Tech/B.E.
The main advantage of pursuing diploma is to get the good job within the short time duration.
It will be very helpful for you in becoming an engineer.
I hope this helps.

Goodluck!
