I'm in 12th class... Is it possible for me to work in a call centre while I work in college as a part-time job?
If you can manage your time then yes, you can opt for a part time job in calling as it would be related as work from home kind of profile and for that all you need to have is good communication skills. Also, you can upload your resume on various recruitment websites available like naukari.com, shine.com, monster.com etc as you will start getting the calls from the companies if you meet their requirements and other criterias but as per my view I would say better to focus on your studies rest depends on you.
Good Luck!!!
