Since GGSIPU holds IPU CET 2018 for huge number of programs, CET schedules are updated at different times. Be clear of CET code, that is for B.J. M. C. its 126, for 2018 online counselling admission will be held for 10 programs one amongst which is B.J. M. C. therefore the dates and counselling are tentative and liability to change so it is advised to check the university website regularly after the declaration of CET 2018 results for any unforeseen change in the schedule.

Your chances are more to get a college. I hope you get this college.

Hi Diya,

Delhi University does not hold any course named BJMC. It holds three courses in the field of journalism. I.e. - B.A. (journalism honors), BA (Hindi Patrakarita) and BMC (only in IP College for Women) (check DU's website for the colleges that are offering B.A. Journalism honours and B.A. Hindi Patrakarita).
For B.A. (journalism hons) and B.A. (Hindi Patrakarita) there is no entrance, there is proper cutoff range for that. For BMC there is an entrance exam and the topics that are covered in that exam are as follows:-
Entrance's syllabus includes English communication, current affairs and a little portion of static general knowledge.

You cannot do your Bachelor's twice. But, you can apply for Masters in journalism and mass communication. It is the option you should go for (MJMC).

What is your category as admission depends on category only?

Hi Amit!
There are no tips as such. In the counselling process, you will just have to see if your rank is suitable for any college. You will then have to make a decision which college you want to select out of the ones you are eligible for. You will be provided with a form, that you need to fill up with your details, college preference and submit other necessary documents as and when your rank will be called upon.
