My recommendation is that you try all of the surveys. Even look for surveys in the "tasks" section. I never expected to qualify for more than one or two a month, but I found that if I'm persistent and check often, I can usually find one a day. The surveys on the left hand side of the FC surveys page are easier for me to qualify for. They don't pay as much, but it all adds up. Sometimes I can get disqualified for 10-12 times in a row, then, boom, I get to take one. I used to give up after a few disqualifications, but now, if I have enough time, I just keep trying until one clicks. It's made a huge difference in my account totals.
