Is average the same as mean?

Yes, in this context, the "average" we calculate is the arithmetic mean. You sum up all values and divide by the count.

How does a zero affect my average?

A zero is counted as a score. It adds 0 to your total sum, but increases the "Number of Subjects" count by 1, which heavily dilutes your average. This is why missed assignments are so damaging to grades.

When should I use this instead of the weighted calculator?

Use this simple average calculator when all your tests or subjects hold the exact same importance (weight) in your final grade.
