i have been talking with this girl in my history class, but we are always with her friend, and I am having trouble to isolate her so it would just be and me and her, any tips on how I could isolate her without sounding too interested?

Take her by her little hand and boldly lead her away.

Depends on the situation. I would say "Let me borrow your friend for a second." or "Come help me with something." something along those lines that's an excuse to isolate her.

Use a wing. Invite them both to do something.

'I wanna show you something' 'Lets get out of here' (More direct) 'Ever had (Insert foreign name here) whiskey? Its awesome and you wont get it anywhere in this country, lets go to my place and have some!' 'I'd love to play a few songs for you on my guitar, lets go to my place and ill show you' Remember to always make the suggestions and NEVER 'ask' her, and yeah it does depend on the situation and how attracted she is to you, if she's v attracted it might be worth being direct but it always looks good when you suggest something, you ask why and you give them a secondary reason, like 'Wheres your BF tonight?' "I dont have one, why?" 'Wanna make sure someone gets you home safe, it's dangerous out there' (Thats your secondary reason, the primary is to see if she has a BF or not)
