Hi aspirant,

Once you enter a good college your previous JEE main marks doesn't matter at all. But in order to get good placement you need to be in a decent college which is not possible without high scores. If you are not confident about your jee main results you can appear for other entrance examinations and find a good college for you. There are many other top engineering entrance examination which include:

• WBJEE
• VITEEE
• BITSAT
• COMEDK
• MHT CET
• AEEE

Now if you do not want to appear for other examination you would have to settle with an average college that may not guarantee you a good placement opportunity.

Hope it helps!!
