For the past couple of years I have been building educational digital content with a view to provide free online education to students preparing for competitive exams for engineering admissions. The response of students so far has been quite encouraging and I'm planning to expand the activity from part-time basis to a full time activity. In order to push forward this activity, I'm desirous of forming an organization which will provide free tutorials to learners and depend on donations to meet its expenses. The organization is envisaged to be quite slim and hire only academicians.
I'd like to know the pros and cons of registering such an organization as a Society or a company under section 8 (not-for-profit). Any advice on the legal structure of such an organization would be welcome.
