Just be honest in your responses to the surveys. I joined last May and so far have been able to cash in for about $100. If I find myself in a survey that is beyond my expertise, I just close out. So what if I get no points for it. I recently found myself in a survey for retirement funds. My husband and his accountant takes care of that even though I try to stay up to date. I muddled my way through it. Never again. It took all the fun out of it trying to remember what he has told me in the past.
