changing order based on other cells [closed]

I have a list of only names in "sheet 1" (1-Mark 2-Jack 3-Kim) and I use this sheet as a data source for another sheet in A:A, "sheet 2" where I input the grades next to the names in B:B (1-Mark:5 2-Jack:6 3-Kim:10).

Now if the order of names in the "sheet 1" changes (1-Kim 2-Jack 3-Mark), how can I make the row order of grades in "sheet 2" change as well? In other words is there a way I can make sheet2 look like this (1-Kim:10 2-Jack:6 3-Mark:2) instead of this (1-Kim:5 2-Jack:6 3-Mark:10)?

I am attaching the actual sheet
