For example, a student who took Spanish, English, History and Math got an average score of 8.55. Then they took Physics and Chemistry exams, and got a 9 and a 7. They want to study Architecture, and the University they want to study at considers Physics more important than Chemistry at that degree, so their 9 will turn into 1.8 additional points (9*0.2) and Chemistry in 0.7 more points (7*0.1). The final score will be 8.55+1.8+0.7=11.05 out of 14 points possible.
