SQL to update column

I have a table with following columns:

id(PK), name, score_1, score_2, score_3, rating

First I have the data for all columns EXCEPT rating. Then I want to update "rating" for each row using this rule

if (score_1 + score_2 + score_3) > 90: rating = A
if it > 80 but < 90 : rating =B

How to write this sql ?

You would need update statements. The easiest way to do this is to have one update statement for each letter grade. Try write an update statement for the first one and post here if you get stuck.
