Many of the names and places will be familiar to those who watch The History Channel series Vikings. BBC's adaptation of Bernard Cornwell's Saxon Stories chronicling the life of Uhtred of Bebbanburg (based largely on Uhtred the Bold of Northumbria, d. 1016).
To score an A* grade for A level Psychology (AQA A) you must score at least 320 UMS out of 400 with an average of 90% at A2. So in basic terms you need to score 90% over Psya3 and Psya4. You can score 85 UMS for Psya3 but then score 95 UMS in Psya4 as that would average out at 90% over the A2 units.
Example of a weighted average calculation: Assume you have taken five quizzes with the following scores out of 10 possible points. 10 pts, 5 pts, 10 pts, 10 pts, 10 pts. The average score will be 9 pts.average = (1/5)(10 pts + 5 pts + 10 pts + 10 pts + 10 pts) = 45 points total / 5 = 9 pts The low score doesn't shift the average down much because the four 10 point scores weight the average toward nine. Here the high scores occurred 4 out of 5 times or 80% of the time.ou can calculate the weighted average in the following way. Literally what happens in the calculation is average score = [40 points + 5 points][1/5] = [45 points] = 9 points. Assume you have taken five quizzes with the following scores out of 10 possible points. 10 pts, 5 pts, 10 pts, 10 pts, 10 pts.
