Criminal Law Eligibility

Hi Jasmine,
Any 10+2 holders are eligible for BA/ B.Sc. Psychology as well as BA Criminology. In India, few institute only offer the course such as BA Criminology and Police Administration from University of Madras, Chepauk, Chennai as well as Annamalai University. You can study criminology as a subject in LLB too.
The duration may vary based on course. The Training and Placement Unit of the Institute is responsible for providing world class job opportunities to the undergraduate and postgraduate students after graduation for suitable jobs in the industry and various private and public sector organizations.
No institute can guarantee you placements. It's just purely based on how you utilize your abilities and skills at the right time. I would suggest you to contact the training and placement department personally for accurate numbers.
Salary is a function of various factors - i.e. (i) the institute where you have completed your B.Tech + M.Tech. e.g. a graduate from a top institute will command a higher salary. (ii) Your work experience - organization and type of work profile (iii) city - a metropolitan city will have higher salaries as compared to smaller cities and towns. (iv) Your current organization - i.e. where you will be joining - an MNC usually has higher salaries as compared to other organizations. (v) Your work profile i.e. Manager/ AVP, etc. Thus one cannot allocate a figure.
I hope it helps. Please feel free to revert.
Wish you luck.
