Bad memories of the PSAT... Woke up late and was in a rush. Ended up getting a double capuccino and a bagel for breakfast but didn't have time to eat the bagel before the test started. I did drink the entire cappuccino on an empty stomach though, and coupled with the nervousness of taking that test (I was probably one of the only people at my school who realized that test counted for more than just practice) made me feel so sick to my stomach. I managed to finish the test though, got a 130 in spite of it all, and a nice 4-year National Merit Scholarship to boot.
Plus, in my case, it was a very good predictor of both my SAT score (1400) and my success in college (3.7 overall). But I do realize that some people's abilities are not demonstrated best by tests like that. But you should try to do well on it (you CAN study for it by the way) as it can help a LOT when trying to pay for college.
