¿Cuál es la diferencia entre total score y aggregate score ?Puedes dar oraciones como ejemplo.

Total score is calculated like this: Say you took a history test. There were 20 questions. The teacher would divide 100/20 = 5 points each question. Say you got two questions wrong. Your total score would be 90.
Aggregated score: Say you took an exam so you could teach English at the high school level. The exam had 300 questions. Aggregated scores assess your knowledge over a battery of factors. Just because you have weakness in one element to teaching English, a strength in another elements could pull up your score so you could receive a passing score. Here might be the assessed elelments:
American Lit.
Bristish Lit
World Lit
English grammar
Planning instruction
Guided instruction
Instruction Assessment
You would answer questions from these 7 areas. You would receive a score for each area. Those scores added together (or aggregated) would be your final score. (which would determine if you pass or fail.) Then each state would set a score each English teacher must score on that exam to receive her teaching certication.
