How to tell if a girl likes you in school
Watch to see if she pays attention to you when you speak.
If a girl likes you, there's a good chance that she'll seem attentive and focused while you're talking in class, or if the two of you are in the same group conversation. Be nice and friendly, and also pay attention when she talks.
Be aware that this doesn't necessarily indicate a romantic interest. But, it's a good sign that a girl respects your opinion or likes talking with you, which can indicate that she does like you.
