Hello Chandhan,

Yes you can join in any lower college and you can write Jee again . But if you again get less marks in coming year it might be problematic that you have to continue in the same college. But you have an opportunity of writing again in april,use it well. Don't waste an year ,if you have a chance in two months. So prepare well and give your best now.  Incase if you are joining in low college and next year you are getting good marks that's fine,but i feel like you can't concentrate on both i.e,college and mains at a time. So,use the chance now.
