No, you cannot fill the IPMAT form if the deadline has passed. The application process for IPMAT is usually time-bound, and the deadline for submitting the application form is strictly enforced. Once the deadline has passed, the application portal is usually closed, and no further applications are accepted. If you have missed the deadline for submitting the IPMAT application form, you may have to wait until the next application cycle to apply for the exam. It is important to keep track of the important dates and deadlines for the exam and plan your application process accordingly. However, if there are any exceptional circumstances such as a technical glitch or a website error that prevented you from submitting the application before the deadline, you can contact the exam conducting authorities or the admission office of the respective institute to inquire about any possible options or alternatives available to you.
