Whether you’re giving feedback after watching some commercials or letting people study your brainwaves while you sleep, there are scores of social and medical researchers out there that welcome college students with open arms. That’s not to say you should embrace every opportunity, but new products need testers and there are plenty of low-level trials you can participate in. Start with the US government’s official clinical trial website, then try contacting local hospitals or companies directly. And college campuses are often full of students and professors hosting research, so look on your school’s website for these opportunities too. Word to the wise: if you earn more than $600 in your clinical trial adventures, you'll need to declare your earnings on your taxes. Also keep in mind that as the payment goes up, so too will the commitment—as well as the potential risk.
BigSpot.com is an easy way to earn some money on the spot by reviewing products. If you have a car, let people rent it or sign up as an Uber Driver in your free time. Vancouver is pretty busy and one of Canada's largest cities, so no doubt there will be quite a bit of Uber users. Task Rabbit is another way: depending on your location, it sends you on a lot of tasks (for example, Walmart sends you to take photos of their products, etc.) Fiverr gives you five bucks for doing certain tasks: like, writing a love letter, or attempting to eat wasabi. Field Agent pays you to check prices.
The first thing that you can sell in college are the notes you take in class. There are many ways to do this. Almost every major campus typically has a note-taking/note-selling service on campus. For example, the University of California, San Diego has A.S. Lecture Notes, which pays note takers and charges note buyers. However, there are also online services such as StudySoup, which allow students to sell their notes online. There are students who are making over $5,000 to $10,000 selling their notes.
This is a very unique idea. You can earn money by creating and selling your own T-Shirts! All you need is a photo editing software for creating designs, and a little investment on your part. Create interesting event-related t-shirts, and prompt people attending those events to buy them! For example, you can create shirts for seminars, social events, parties, etc. It’ll take some money to initially produce those T-Shirts, but you can sell them at a profit to gain more than what you spent! A friend of mine started with this idea, and now, she has a small business and a brand with a website, where people can choose from the available designs, or order a custom-made T-Shirts according to their desires! Great huh? Who knows it could evolve into a full-fledged business for you?
Along the same lines as trivia, you can get paid for just using your mobile phone and allowing companies to know what you're doing on it. For example, Nielson Mobile Panel is an app that you can earn rewards on just for having it installed. It will take snapshots of what you're doing and use those for advertisers to know more about your demographic. It takes away some privacy, but you get paid for it.
That’s my plan. No kids, no spouse, parents deceased. I’ll never be able to retire. On PSLF, but forgiveness not approved until 120th payment. Many are not being forgiven now. I take courses to stay in deferment. FedLoan bases payment on gross; not net. How does that make any sense?! After bills I can’t afford the payment. I have 3 grad degrees. Was supposed to be a psychologist. APA & NCE won’t accept my 15yo degrees for the national exam. So I teach at a CC. Over 180,000 in debt now and it grows monthly.
Cold calling still exists, and businesses are always looking for people willing to man the phones and make calls. Many companies hire this in-house, but there are also firms that hire telemarking professionals to man phones as well (especially around election time). If you don't mind being on the phone for several hours and getting hung up on often, this is a good job for college students.
Do you have a great idea for a product but don't know the best way to go about creating it? Well, you could submit your idea to Quirky. They'll screen your idea, and if they like it, they'll either develop it themselves or in partnership with a major brand. In the end, you'll get a cut of all the sales from the final product. For some inventors, this has only earned them $1,000s, but others have earned $100,000s through the platform.

Did you know that those people asking for your signature outside the grocery store are typically paid to get you to sign up? Contrary to popular belief, they aren't pushing politics because they care. They are pushing for your signature because they typically get $1-$2 per signature. If you could get 30 people to sign up per hour, you're making $30-$60 per hour. Not bad.

Freelancing is one of the toughest, but also one of the best paying methods of earning money. Toughest in the sense that it is hard to get a freelancing job. But once you get one, it’ll be worth the effort. Mostly, hirers are looking for experience, which most students don’t have. But you can increase your chances by joining multiple freelancing websites. Here is a list of the top freelancing websites you can try your hands on. Alternatively, you can do some other freelance tasks which don’t require an internet connection!

If you have anything you don't use anymore, and it's too large to sell online, Craigslist should be your go-to place to sell stuff. In college, you may want to sell all your furniture before moving home from school at the end of the year. Depending on what you own, a few $100 might be better than storing it or transporting it back with you. It's easy to setup a listing and sell anything on Craigslist.
A lot of students choose to use their art for earning money. If you are good at arts and crafts, you can sell handmade, customized cards to people. You will find a large customer base in your college itself and you can use college events to exploit the option. Keep track of events like valentine's day, prom night and teachers day and approach different colleges to allow you to put your stall which will maximize your sale.
You can apply for online internship for content writing, proof reading and designing. There are people looking for candidates just like you and these are not very technical fields so you can easily do these things after college hours and make money while doing something you enjoy. Keep looking for internships on various websites and look for 'freelancer' option. Clear things out about your timing and number of articles or designs with the employer before starting the work.
Search for freelance writing and editing gigs. The rates for these jobs vary: you may be paid by the word, be offered a flat rate for a project, or in some cases can be paid an hourly rate. You typically won't be able to retain copyright over your work or collect royalties, however. Even so, by doing freelance work you can build a portfolio and make valuable connections which may later pay off with more stable job opportunities.
