Hi

Short answer: Yes

Long answer: Who cares? Do YOU like HER? If so then go for it, even if she is only mildly interested its your job to take that and turn it into more interest.

Unless you're a rock star girls aren't going to give you a written declaration of interest signed and copied in triplicate. Its up to you to make the moves.

Well, if she's looking at you in class she is certainly not turning you away...

Idk why but I've always seen women texting openly infront of me as a sign they want to give me their number, no real proof behind it but it seems to happen very often.
Try shaking her hand, and hold it there (not forcefully), does she keep your hand held? This is a variation of the high five hand hold thing where you get we to high five you and you hold her hand for a second and see if she leaves it there.
Also if she really likes you this test will show it
Talk to her, end a subject and see if she continues the subject or starts a new one, HUGE IOI
"...and that's how I beat up a bear"
"oh that's so cool"
"thanks"
You ended the convo, but if she then says
---"what did you do afterwords?"
she definitely likes you

Hi

Maybe she is just shy and insecure about her self.
