The purpose of this forum is to help you learn how to do math -- not to do your math homework for you.

Take a pencil and paper and write the list of scores in ascending or descending order and then answer the questions.

You can also sort the scores using a spreadsheet like excel if you know how -- just type the scores in a column and use the sort feature.

My deepest condolences to those students who get such assignments from their teachers.

And my advise to them is to run from such teachers as fast as you can.

Because the matter is about saving your mind / (your brain).
