If you haven't maxed out your financial aid, you can start over at a new school- the new school will check your prior classes (IF you choose to provide them that transcript information- you don't have to, but possibly some previous classes will transfer to your new school and to your new degree plan) and they will tell you what will and what won't transfer forward (meaning at the new school you won't have exceeded the maximum allowed credits for your degree plan). Then you will be able to get back on a new track. From what it appears you have posted, you have reached a dead-end at your current school as far as credits, attempted credits, etc., but you have not maxed out your financial aid. I'm in a similar situation, classes were not available to complete my degree plan- so I'm moving to a new school that has a specific class track 'block' to meet the degree goal, and you don't have to scramble to hit or miss your chances of getting into the required classes. It's been a real nightmare. In the end, to answer your question: If you go on to a new school, your issue of attempting to remove previously attempted hours will become a non issue, since you either passed a class and the class hours will transfer to the new school, or you failed the class or in some other case the completed or attempted class hours won't transfer to the new school.
