Joanne is absolutely right. Ideally you should consult an advisor.

Since I'm on the BS General Business track, I'm attaching my degree plan and an alternative degree plan. I think it should give you an idea about the upper level credits, and the advanced business credits. I think Hunter explained it correctly, but sometimes it's easier with visualization. Page 1 on the PDF file is my current degree plan, and page 2 was my previous plan. I decided a few weeks ago to switch from ECE Ethics (UL) to DSST Ethics (LL), so I changed from DSST Intro to Business (Lower level credit) to DSST Business Law 2 (Upper level) to compensate for the loss of UL credit. Both were approved by advisement. BS-BGB.pdf
