Dear Ashutosh,
The best option that I can suggest you is to go for one year Advertising & Public Relations course from IIMC. The course will teach you all the aspects along with providing you various job opportunities. You may also refer the link below:

You may also join Mudra Institute for the same. Both the institutes are good.

Giving details of each and every test that is conducted for journalism and mass communication is not an easy task. It is advised to initially think of the college you wish to get into and then ask for the details for the same.

Hi Dhruv, start taking mock tests regularly now, its very essential and will help you understand where you need to improve more and wil give you an idea where you stand.
Good Luck

Hi Priya
Little confusion at this stage is perfectly okay as you have advices and suggestions coming from all corners (read, relatives, cousins, uncles and friends). If you wish to go in the field of investigation there could be various paths like B.Sc Forensic Science, Investigative journalism, News Reporting, RAW or IB but you need to be very strong physically, emotionally both.
Another option is research, where you are investigating about may be people, data, numbers or things. Do make a check if your skills match up or not.
