It was a harder exam than I thought.
Some points to study: Algebra and Geometric concepts, chemistry concepts (be sure to know the major symbols, like Nitrogen, Oxygen, Calcium, etc.) and weird as it sounds, basic electricity concepts (I had a questions about Ohms's, and was clueless).
I ran out of time on the reading comprehension. I read each "story" twice, and then I didn't have time to answer the questions. Read and understand, but watch your time. Practice reading news stories quickly, but with understanding of them.
Since we couldn't use calculators, I really spent time brushing up on doing math problems without one (like what problems do you do first, the ones in brackets or parentheses), and did a lot of "solving for x".
If you have time left over after finishing any questions, go back and check your work. I found 3 in the math section that I had misread and marked the wrong answer.
Also, I've learned from that exam and from my nursing exams, don't spend too much time on any question. Make a light mark on your answer sheet so you know you skipped one, and go back to it. We're learning now the same thing with our exams. Read the question, see if you know the answer w/o looking at the given answers, then see if your answer is there. If not, does one make sense or is similar? If you're stumped though, move on and come back. Time does move by quickly.
Good luck to you!
