I have a question about this girl, need to know if she is at least interested in me....? ??

so this girl i know her in church and college we go to the same church, and we have 2 classes together. she is always with her friend. This whole time i didn't have any idea that they went to the same church. i started talking to her and her friend about a 2 weeks ago. when we do a project outside i put my shades on and do my work, but i can see her looking at me. In church she gave me a hug and said if i took a test yet? idk if this is just friendly talk but she is really nice and sweet to me. I am good looking and always dress nice... anyways i was in the cafeteria this one time and got thirsty, i saw her sitting in a place and didn't say hi i wanted her to assume i didn't see her, i got thirsty again and bought something else... she then left, i was walking down to sit down and we crossed paths and i said hey and she was like hey whats up? and gave me a hug... i asked her what she was doing there and she said she forgot her backpack..

who forgets their backpack?

anyways i had class with her and i said hey and she was like hey and called me by my name... i really like her and i need to know if she at least show some interest. she is really nice and she asked me something about a quiz in church which seems odd, i really don't want to get hurt but what if she is just being christian nice? i need more answers.... also she was looking at me in church. who knows? please help!
