I've received multiple questions on this topic, so I decided to take the point and make the grade improvement option more open. 

So, although I have stated otherwise before, I will allow you to keep the highest grade between the MAP and the Exam (components 1 and 2). 

Moreover, as stated before, if you worked on a project and take the full exam, you can still keep the project and presentation grades and replace only the MAPs component. Only in case your exam grade is actually better, then you get the exam grade.

I hope this helps.

Best,

Carla
