Hello,
You can fill as many choices as you want in JoSAA choice filling form. But it is to be noted that you select the institutes and branches in which you are interested to get seat. Do not select a college or branch in which you aren't willing to join. You should also check the fee structure of the institute before making a list of preferred institute. The details related to the fee structure will be available on the respective institute official website. You have to visit the individual institute official website to check the information. To know the institutes in which you may get seat you may use our JEE Main college predictor or JEE Advanced college predictor depending on the score through which you are applying for admission
