BJMC

Hi Raj,
If you are more inclined towards journalism and mass communication as compared to BCA, it is a correct decision because pursuing a course without having an interest in it is not apt.
Yes, it is possible to switch your course but you have to start your BJMC from the very beginning.
Eligibility criteria for taking admission in IMS, Noida for BJMC:
Candidates seeking admission to the BJMC Program must have passed 10+2 (or its equivalent) examination from a recognized Board / University. Candidates appearing for the qualifying examination in 2015 or those who are awaiting their results are also eligible to apply. Their candidature, however, shall be considered, subject to their clearing the qualifying examination conducted by IMS Noida.
The form provided by CCS University has to be filled and submitted to the Institute. The Institute will shortlist candidates and produce a merit list on the basis of the performance at 10+2 level. The candidates are allotted seats in category (General / Management) on the basis of their merit in Joint Entrance Test (JET).

If you want to become a journalist and if you are in 2nd year of B.Arch then first you complete your graduation then do MJMC because if you do a BJMC then simply it is a wasted of time and MJMC is a compressed from of BJMC and the same syllabus has taught that are in BJMC so it is no value to do BJMC and also our college provide you a labs like Editing lab, Photography lab, AV labs, where you can learn the basics of journalism field. Our faculties our very good and of course a lots of knowledge to provide you. Between MJMC there is opportunity to do a internship so you can earn a lots of knowledge. And you don't have any problem in your future. Also in our college there is a practically learning of the subject not theoretically. Also our dean ma'am and director sir will take us for the field work where you can learn the management of field work. So this is the easiest, simplest an according to me the best way to become a journalist.
