Hello Aspirant

For JEE Mains 2021, the eligibility criteria with reference to class 12th percentage is that you should have passed class 12th. Earlier the criteria was that the student should have an aggregate score of 75% in PCM.  But as per the revised JEE Main eligibility criteria 2021, criteria of 75% aggregate has been removed. So if you are well prepared for JEE Mains 2021, then you can surely give this entrance exam. Do not worry about your 12th marks. As now you only need your passing certificate of class 12th irrespective of the marks obtained. Coming back to your question, do not think about college and job through JEE at present. JEE Mains is a national level entrance exam which is not so easy to crack. You need a lot of practice to crack it. So just give your best in preparation. Do well in your exam. Try to solve as many sample papers as you can.
If you get qualified with a good ranking, you will be surely getting a good college with good placements.
I suggest you to give other entrance exams as well for getting admission into engineering colleges as JEE mains is not the only entrance exam through which you can enter engineering college.

Good Luck!!!
