jdjdjd, Thank you.
Don’t get discouraged. This has an easy answer. I have been in this situation myself. See my other post.
Look up an online tutor. There are a lot of resources on the Internet these days for places you can get help. There are even videos on YouTube you can watch that will explain subject matter to you better than the teacher. I have had to do this myself for some of the classes I take. It really works.
