Lucky. What do they do in the tests? Also, im assuming for one to participate in a medical research test, you would have to be 18. Correct?

But other ways to make money, Find old people on your street or in your neighbourhood and ask if they need any help around there house/yard.

Could pan-handle aswell, dress like dirt, then go downtown, you can make some money there haha, thats if your desperate.

But seriously, get to a job help center, make up a resume and apply to every place available, not expecting high pay, minimum will be the standard.

Grocery stores
Fast Food places
Bus-Boy
Dishwasher
Labour
Etc..
