Hello ,

There is nothing like best or worst course , because every course is designed to provide you knowledge and skills required for job .

Now as you have chosen to do polytechnic after 10th , you are going to have options of branches same as engineering . Now , it is upto your interest what you want to choose . If you like computer technology and wants to learn about software etc go for CS , if you want to learn about electricity and power supply etc go for electrical , if you want to learn about machines and its parts and application of machines , 3D printing etc go for mechanical . Apart from these many other branches are also available like chemical , electronics etc .

I would like to tell you first find out your interest and go for that and if you don't able to find your interest then look for the opportunities available in job in a particular field .

So , first look for interest , if not able to find it look for branch with more opportunities.

Hope this will help you .

Good Luck .
