In order to reassess a standard, the following requirements must be met:
You must have no missing grades in Skyward.
You must have the appropriate homework completed.
Example - If you want to reassess 1.1A, you need to have the homework completed that has "1.1A" at the top of the page.
If there is not a homework associated with the standard you need to reassess, speak with your teacher about what you will be required to show in order to reassess.
You should prepare to reassess. You have access to the exact reassessment question here in this Google Site. You should review that question and consider how you would respond to it. If you would like, you can pre-write a response to show your teacher, so that you may have a discussion with them about it before you reassess.
Once those requirements are met you can reassess by bringing the completed homework to your teacher during tutorials, and tell them the exact standard you are wanting to reassess. Your teacher may ask you questions about the standard to see if you are indeed ready to reassess that standard.
