I graduated in 1988 i only learned adding subtracting and multiplication and division i start online classes in may and i dont understand anything about algebra
If you'll be using a textbook for class, perhaps you can buy it in advance, or gain access to the online textbook so you can begin getting familiar with the concepts in algebra. That might help lessen your anxiety. Plus remember you're going into the class to learn; no one expects you to understand the concepts in advance. I know after 25 years starting college might be stressful, but, as an instructor (and a class of 1988 grad too I might add), we're there to help. Don't be afraid to speak up when there's something you don't understand. Best of luck to you!
