A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50 multiple choice question by topic, as the questions alternate between the two. The problem-solving section could stand alone as a chemistry quiz, but the third section has both chemistry and biology essay questions. Perhaps you could use this as a resource for questions that you could incorporate into your own test.
