Differences Between Different Direction Notations

[jwj11]

So I get that [25 degrees North of East] is a line that is 25 degrees above the east axis.

But what about [E25S]

Is that [25 degrees South of East]
or [25 degrees East of South]

My teacher says that [E25S] is [25 degrees East of South]

but based on that notation I think it is [25 degrees South of East]

Please help me determine this because he has deducted marks for it. Any credible internet sources would be helpful.

wait so does that mean it can be interpreted either way? based on your experiences which is correct?
