How to calculate your weighted grade. To calculate your weighted grade all you need to do is multiply the mark you got in each part of your class by the percentage it is worth towards your final mark. You do the same for each part of the class and then add the answers together.For example if you got 85% on a test worth 20% of your final grade and 70% on an assignment worth 25% the sum would be (85 x 0.2) + (70 x 0.25) = 34.5% out of a possible 45%.To work out your weighted average so far you simply divide 34.5 by 45 and multiply by 100 = 76.67%.ou do the same for each part of the class and then add the answers together. For example if you got 85% on a test worth 20% of your final grade and 70% on an assignment worth 25% the sum would be (85 x 0.2) + (70 x 0.25) = 34.5% out of a possible 45%.

Seasons are fundamental to how we understand the climate and the environment, but for hundreds of years academics have argued that their specialist field is the one which defines official start of autumn. In meteorological terms autumn begins on September 1, as each season is defined as a three-month period. Astronomers base the date of the seasons upon celestial events, in this case the autumnal equinox, when night and day are roughly equal length.
