Note that the methods used in grading this exam will depend on the professor’s preferences and the college guidelines for this type of grading. The chart below outlines the general percentile rankings estimated for the ACS General Chemistry exam on a national level. With percentile rankings, the ranking you get, such as a 90th percentile, indicates that you scored higher than 90% of the students on the national norm. In percentile rankings, there is a good chance that the questions you do not know how to answer are also questions that several other students have trouble answering. Your score is based on a percentile ranking. To pass the ACS General Chemistry exam, you must answer at least 50% of the questions correctly. If you do not know how to answer a particular question, it is best to skip it and go back to it once you complete the questions you do know. A scratch piece of paper will be provided, and you are allowed to bring a non-programmable calculator if you would like.
