You have selected more than 60 credits in the Special Assessment Period (SAP). Regulation XX sys that students may not take more than 60 credits in SAP. For more information, see the When Does Reassessment Happen section of the FAQs. 

You need to either go back and review your selections to select Next Academic Year for your reassessment, or (if possible) reduce the number of credits for which you are registering.

Regulations can only be waived in exceptional circumstances, and you should speak to your Programme Administrator before submitting these choices to see if this would be applicable to your situation. If you have already discussed a waiver with an administrator, you may select OK.
