Hello Pratik

If you go for Class 11 & 12 you will have the Physics, Chemistry, Mathematics Subjects. Whereas Polytechnic you will have core subjects which are part of Engineering. If you go for Class 11 & 12 you will have lot of chances to your career but if you choose Polytechnic you have only one option. If you learn the concept clearly you can shine every where. I can't say which is best because both of them have there value. Some are Interested Polytechnic and some are on class 11 & 12. 

Hope this will helpful

Good Luck.

Hello Pratik

Either way you can go for engineering. if you go through 11th and 12th in science you can join the engineering as Regula student. You can also go for Graduation in engineering in IITS, NITs, GFTIs. However if you go through Diploma you will not be able to study your graduation in reputed Institutions like IITs, NITs. You have to join the college as a Lateral student. Some of the colleges donot give admission Lateral students for Graduation studies. But you can have a very fundamental and practical understanding of engineering through Diploma. So according to your Choice you can choose any of the way from these two. Hope I solved your query.

Thank you.

Dear Aspirant,
Both plays their own role.
But in case of polytechnic
You will get more knowledge about your branch.
You will do projects in your polytechnic college so you will gain more knowledge.
Doing Polytechnic is a better way for gaining knowledge about your branch.
And in case of 11,12th you will study science and maths
In case of polytechnic,you will do much things in maths.
You will not study much maths in polytechnic
So choose wisely

Hi ! For engineering 11 and 12th is very important and good also. Polytechnic doesn't technically makes you strong to attempt JEE main exam. Moreover 11 and 12 th is vast and hard too which is perfect for JEE advance. It also helps in 1st year of college. So hope you understand and best of luck to you.
