Nandini, There are no colleges or Institutions that enrol you for CA Courses. You have to register individually at their official website which is https://www.icai.org/new_post.html?post_id=721&c_id=120 . For being eligible for CA Foundation, you should complete your 12th in any stream and complete a mandatory study period of 4 months. CA Foundation exams are conducted twice every year. During May and November. So if you are appearing for your 12th now, you can appear for November session. First you need to register with ICAI and then fill the application form for November session. The May session registration has been closed. For more information, please check the official website at: https://www.icai.org/post.html?post_id=13633
