If you are a student who is having a hard time finding a part-time job that fits into your school schedule, you should know that you may be able to earn just about all the extra money you need right in the comfort of your own home. You can make money online at your convenience, taking surveys and testing products you get to keep. It is a very real and flexible means of earning income and if you know where to look, it is very simple to get started.

First, you need to find a free list of survey companies. Note that I said "free" list, because there are a good number of websites out there that will offer up their database or list of survey companies for a nice fee. You don't need to pay for a list, you should be able to find all the information you need without paying a dime.

Next, you will need to register for the individual survey companies and confirm your registrations in your email. You may also want to set up a separate email for your surveys, because you will get a lot of email and it might overwhelm your primary email address. When choosing to register for a survey company, keep in mind that compensation varies with each survey panel, however, you will want to register for as many survey companies as you can, so that you have a lot to choose from. Even the companies that only appear to offer sweepstakes entries as compensation are good candidates to register for, as they also do product testing (where they send you stuff you would normally buy, and you get to try it and keep it for free), focus groups (the big money--$150/hour) and occasional great paying cash surveys. You just never know what they will send you or what you qualify for, so it's best to register for them all and filter them out once you receive them in your email.

Lastly, you need to make sure you finish-up your registrations by completing any additional personal profile information the companies ask you for. This will help them determine which surveys to send you, to better your chances of qualifying for them. After that, you just start earning. As long as you keep your income expectations realistic you will not be disappointed. If you don't like the compensation, don't take the survey and check out the next one. There are always plenty of opportunities when you are registered for multiple companies. There is literally nothing else that will let you earn money at your own convenience --even if it's 3am and you are in your slippers!
