You can work very hard all semester, get good grades on the written work, and still fail the course. There are no lectures in this course. You are on your own just you and the textbook. Fortunately, you will be able to answer this question very early in the course. Each week there is a quiz on the reading assignment from the textbook.
Most weeks cover more than one chapter in the text.
Your grades on the quizzes will be a pretty accurate guide to the grades you can expect to earn on the midterm and the final exams. If you have always done well in science courses, there is a good possibility that you can succeed in this one. If you have always struggled with science courses, you should not take this course. By the way, I am referring to university science courses, not high school science courses. The quality of instruction in high schools varies tremendously you might have done very well at a very poor high school, and that would not be an indicator of your chance of success here.
