My marks are not good in JEE mains. Which field should I choose??

bro there are many fields open for yu. if you are interested in any field choose that. yu can also do management also. There is no harm in it. yu can search on net about best colleges which conduct their own exam. plz don't drop yur year bcz drop out is not a solution. try yur best yu can also sea

you can choose any field as it depends on your interest but as u score less in JEE you can prefer electronics,extc,automobile or production.

you can choose other colleges which do not have jee main score as their entrance procedure

Dont decide stream on the basis of your JEE marks because choosing a stream based on JEE score wont help you in the long run , go for the one in which you have the maximum interest . You can either take a drop and prepare again or go for some good private engineering college
