So, the past week I have been asking Chegg experts questions about my homework problems relating to sign testing and runs testing. The people who have been answering have been different and they all have gotten the answers wrong. Chegg is good for simple math problems that everyone should know and not the hard statistic and probability problems only math majors know about. Don't get Chegg if you are in a college math course, but if you are in high school or middle school then get Chegg. The experts at Chegg are not experts!
