I've come across an issue I'm having problems solving and was curious if you guys had any great ideas. One of my students is working on his private written exam and is having trouble passing it. I had him take practice tests at home using the cessna kit which allows me to see scores and what questions he missed. We would then go over those questions together. He was getting high scores (80s/90s) so I let him take the test. He failed. I wasn't sure what was going on so I asked if he was using a book or a cheat sheet at home. He said no. He told me he thinks he may have just gotten nervious. My solution for that was to have him come in and take practice tests on one of our spare computers to put him as close to the environment as I could and also be there to go over questions he missed after he was done. His scores were all over the place, one would be a 72 and another would be a 90. The odd thing was it wasn't in any particular topic. He was missing questions like how to calculate cross winds using a chart just as easily as XC planning even though we've gone over it many times. Eventually he was getting steady scores of 80s so I let him take it again last week. He failed with a 62. Am I missing something I should be doing?
