Kindly predict your college in this college predictor. JEE Main rank predictor is an online tool which predicts the candidates rank range and probable colleges based on the difficulty level of the examination, average marks scored in JEE Main and seats available in IITs, NITs, GFTIs, and other SFTIs.
The rank predicted might not be accurate but it certainly does give an idea to the aspirant.

In my opinion, you should keep yourself cool instead of taking any pressure. JEE Main has been conducted twice this year and a lot of students have given both the exams. Hence, predicting specific colleges is a quite difficult job. So participate in all JoSAA counselling rounds timely. I can only wish all the best.

You cannot shift college, if you are in the same college then you are eligible for 2nd year.
