Study Strategy
I used 240tutoring to study the first AND second time. I have yet to take the second exam, but I felt that 240tutoring was AWESOME. Before I started studying, I literally sucked at most sciences. It was very helpful in getting me where I needed to be, however it wasn't as rigorous as the actual test. Fortunately, they've made a lot of changes to their study guide, so I'm hopeful for the next time I take the test. I feel a lot more prepared.
Testing Strategy
The test was quite a bit harder than I originally expected. Like a lot of people I was really frustrated right from the beginning from all the chemistry they had on there. Eat well and sleep tight the night before, keep a calm head throughout the test. Knock out obviously wrong answers, but be prepared for the last two answers to be for close. Read the questions very carefully, and be sure of what exactly they are trying to ask. Great luck teachers!
