So I am in 6 form in England. There is a girl in the year above.
However, in a week we break up for study leave and I won’t see her again in school. As the year above finish when they leave for study leave.
I think she likes me for a number of reasons
I always catch her looking at me/trying to look at me. We went to a study revision class last week and I started making conversation with her for the first time. I stopped halfway through the conversation to see if she would carry it on with me, she did.
The problem I face is the amount of time we have in school, so not that many opportunities to speak to her. The only time I really see her is first thing on some mornings where she has to stop with about 4 of her mates, it’s on the way to my class.
The other day I looked up to see if she was looking at me and I held her gaze for about 4 seconds of eye contact. Defiantly attracted. During break all the girls in the older year wait in a class where none of my mates or me really go in (mainly because there is no reason to and because they are in their).
The only things I think I can do is either add her on Facebook and start speaking to her on that (however I think it shows low value and shows I am interested in her) or speak to her in school. However I do not know how as there is no other revision class and I don’t know how to speak to her without her mates thinking it’s strange.
Please can I have some advice/tips as I only have tuesday-friday in school.

If you think she's interested in you, then she probably is. Nothing is wrong with adding her on Facebook and talking to her through that, but you will have better results approaching her in person. Why can't you just go up to her before or after class and strike up a conversation?

It doesnt matter what her mates think. It never mattered in the first place and in a week you'll never see them again either. Just talk to the girl, definitely in person instead of on Facebook.

bro, your in highschool. your supposed to do some chodey shit. its no big deal

we used to "ask people out" in highschool (graduated 2009) meaning seeing what you describe and saying "will you go out with me?" and boom! girlfriend & boyfriend.

just walk up to her & tell her you like her bluntly. she will admire your balls, who cares if its awkward.
Direct for the win!

Ok just got major approach anxiety over her friends. I cant see her after class i wont see her. we are in seperate buildings.
