Assignment 1 failures and tentative grade.

[Arrvindh Shriraman]

If your localci reports failed or travis reports failure then your assignment is not complete.

- In such cases, the tentative grade as it says is "tentative". 

You cannot expect the _Grade.json to reflect your actual test scores. Your final score could be lower based on what actually fails.

- Your scores will change based on how your code behaves on hidden cases.
