No I can't consider it as a part time income at all , the reason is you have to get 3000 points to get 3$ , each question you answer you get 10 point . to answer 3000 questions you need time to find a suitable question to answer , it consume time and effort answering .for me it's not even an extra cash till now this is my opinion .besides the sites I am working for it is not even 0.01 percent .
