is it necessary to lock the options and take the print out before locking period,also need to pay any money after locking???

As per your query, you are not required to pay any fee to lock your choices. The non-refundable registration fee and refundable tuition fees have to be paid during the registration process. After the successful registration, the option to fill the choices will be made available. In this step, the number of colleges will be displayed and you can select these choices. The exercised choices will be saved only if you will click on ‘Save & Continue’ button and after finalising your choices, click on ‘Save & Go to Home’ button. It is important to note that if you have registered and not saved your choices then you won’t be allotted any seat. The option to lock your choices is advisable because if you will not lock your choices then the saved choices will get locked automatically. You can take a printout of the page at any stage of the submission of choices. Taking the printout is recommended to maintain your own record of the filled or locked choices.

Good Luck!!!
