First half had 120 total points and you got 81%. So you got 120*0.81 = 97.2
The total points for the whole year are 120+140 = 260
In order to get a full year grade of 80%, you would need to score 260*0.8 = 208
Since you already have 97.2 points in the first half, you'll need 208-97.2 = 110.8. Not sure how you get .8 points, so go get 111 in the second half
