Official grades are only those grades signed and publish at the secretary system. We normally do that after the revison of the 2 exam and the whole assessment process completed, something to happen by 18 or 19 Feb.For those students that want / need to have their grade signed and publish at the secretary system sooner, by 5 Feb, please send me a message in "fast-course-closure" SLAK channel 
This means their grade is final and they will not do the exam 1 revision nor the 2 exam.

Thanks

Pedro Sousa
