Knowledge Test

I took a couple hours off of work this afternoon and headed over to Cirrus FBO at Anoka/Blaine airport to take my knowledge test. The test was 60 questions with 150 minutes of time allowed. I was there roughly 75 minutes and I passed the test. I missed 2 questions, which gives me 97% (70% is passing). At the end, they let you see the questions you missed. One of the questions was about requirements for class C airspace. I put "in communications with responsible ATC facility". This is what my study book has, but apparently they were looking for Mode C transponder. I think this is sort of a trick question, and I question whether the answer on the official test was correct. I know you need a Mode C transponder in class C airspace, but according to the book, some flights are allowed into class C airspace without a Mode C transponder, when ATC gives you clearance, and that's why the book indicates the answer I gave. The other question was about minimum ceiling and visibility requirements for Special VFR in class D airspace. I put 1SM and 1,000ft, but the answer is just 1SM, and there is no ceiling requirement. I'm very happy with this score though, and glad to have the test behind me. I think the only things standing between me and the private pilot cert at this point are more hours of hands-on training, and the dreaded practical test at the end.
