India

To begin with, Delhi is not the only center for Indian Institute of Mass Communication. It has its branches in Dhenkanal, Maharashtra, Kashmir, etc. For PG Diploma in Journalism, one needs to have all the current affairs on their tips along with a stronghold on English/Hindi - depending on the fact that in which language you chose to pursue Journalism in.
GK/Current Affairs:
These include not only MCQs but also in-detail answers for which the candidate needs to have in-depth information about that particular current affair. The long answers generally ask the students to give their take on a certain current affair/GK-related question. One should have quotes/examples at hand to make their answers stand out from others. For this, one needs to have a thorough newspaper reading habit. Current affairs of six-eight months before the scheduled date of exam are included.
English:
One should prepare for homophones (similar sounding words with different meanings), finding errors in sentences, word-meanings and make sentences, and unseen passage. It isn't as simple as it sounds and needs preparation.
Students can prepare on their own or take coaching if necessary.

The answer is a big no.
Audio-video editing requires a candidate to not only learn the intricacies of the software, but also learn minor things like how to dump an audio/video file from the camera/any other recording equipment to the computer. This isn't something one can mug up from text books or internet because it requires the concerned person to learn the skills over time and enhance them for the better under able guidance of the teachers who can help in sorting of the pros and cons one needs to take care of during editing.
Also, an audio/video editor should also have a better insight into how can one record/shoot a certain audio/video in a way that least editing is required on the system. Without practical experience at the editing desk, this will be a task which will be very difficult to complete.
And this holds true for India as well as abroad.

Most important topics to focus on while preparing for B.Arch exams. It has 2 parts.
Part 1 being Mathematics & General Aptitude
