Dear Ojaswini, ideally if you have registered before 30 June 2017, then you have 3 more attempts for CA CPT Exam. These three attempts June 2018, December 2018, and June 2019 are left for students who are registered for CA CPT exam. But if you have registered in April 2018, you cannot write in June 2019. You will have to register for CA foubdation course.
