My Cie as level result

Hello everyone. I have received my as level cie result. Bio 83 A phy 89 A chem 80 A. Is it eligible mark for A* next year or should I retake and how do we calculate percentage uniform mark. I saw some post in order to calculate percentage uniform mark and what I understood is for instance, i have chemistry 80 A and the grade threshold for A in component 12, 22,32 is 89 this year. Does that mean I got exactly 89points out of 140 and A* grade threshold is 180 so I need to get 91 points out of 130 in order to get A*? Is what I understood is right? And how do we calculate for others like phy 89 and Bio 83 or should I wait for raw mark to publish?
