Term 4 Week 3 Daily Challenge (LMS)

Dear all,

The daily challenge for next week is up at the LMS!
You will have 3 attempts altogether!

Please be informed that there will be a new score system! :P

New Score System:
1st Attempt to have perfect score - 100 points X 3

2nd Attempt to have perfect score - 100 points X 2

3rd or last Attempt - whatever score you have X 1

Your queries:

What if I have scored 80 points in my first attempt and I do not want to attempt again... what will my score be?

Answer:
It will then be considered as your last attempt.
You will only get 80 points then.

The multiplier will only be applicable to perfect score! :)
