Is this not victimisation?

Today I hadn't done half my homework when I usually do all of it yet got ranted at more than people who did none at all including one person who hasn't done any homework all year and people in the same situation at me didn't even get a strong word. Later on she started raging at me for paraphrasing despite the rest of the class doing so as well. I also got a detention for the homework when another person just got told to do it for tomorrow.
