Hi Divya, thanks for your question.

Yes, you can appear for IIMC entrance exam provided you have completed your graduation and are born on or after 1st August 1993, (if you belong to general category). 

The application form of IIMC 2018 will be available tentatively from the last week of March 2018 in online and offline mode. You can either download the online application form or you can purchase it from the IIMC centres. The Application fee is Rs 1200 (for general category).

Since IIMC offers a lot of courses, you will have to choose the course(s) of your liking in the application form. The last date for filling the IIMC 2018 application form will tentatively be second week of May 2018.

For detailed information on the eligibility for other categories, the courses available and the entrnce exam syllabus you can refer to this Article - https://media.careers360.com/articles/iimc-entrance-exam

Since I have also done my PG Diploma in Journalism from IIMC, I can say from my personal experience that if you start you preparations even today and keep yourself updated with the most prominent events of this and the previous year by referring to one or two good new papers (viz. The Indian Express), you will have a very strong chance of scoring good marks in the entrance exam and acing the group discussion and personal interview. All the best with your preparations.
