Well, that is a lot of info coming from a newby...
1. You are new... do not expect results right away. PU can be a long and confusing journey, so prepare for that
2. You want to bang the girl in anatomy class, but can't focus on the process. Haha, that is always your worst enemy in PU. Learn to control the force boy... Anyway. Start reading on material and use it on her, but also on the teachers other classmates (male and female), even the janitor, turn your life in a social experiment so to say...
3. You are in the state of mind of not caring but still have AA. Be careful... PU can destabilize you psychologically if you do not self reflect periodically. Seriously keep "self improvement" as you main goal. That is very important! Think about this before you think things like this or put them on paper or a post like this.
4. The push-pull tug game? I know what push pull is, but I wouldn't try it if wouldnt even know to read signals on attraction yet. Start simple man. Read up on Mystery Method (his book) it is very detailed on getting signals (amongst other things). This is a good place to start.
5. About nr. 4. Bullshit about you are playing the push pull game. You chickened out when she got sexual in a convo. You are now saying that "we've broken that sexual convo ice". What? Because she started talking about kissing girls? What did you say back in response? It was probably one of her shit tests. And you probably failed. Sorry if I am being hard on you, but you will learn that you can lose a girl over very sublte flaws over not acting on very sublte positive signals she will send you. At least your post is not very convincing to me that you are naturally understanding these things, so you will need to start studying material and start practicing.
6. She got on her knees in class... I don't get that one. Did she actually suggest oral sex (like moving her head or making her mouth in a round shape)? Are you sure she was doing it on purpose? Than it was either a shit test or signal, or nothing at all. But you didn't respond, so... difficult to say, but probably bad.
7. I am not here to discourage you or something. I was a complete AFC until I was about 25 and never even knew what a signal was or what it looked like. I guess that's why I am so serious about this post. Don't worry about saying something to her in your learning process that will freak her out or dislike you. You will have to go through things like that to get better.
8. But to not completely leave you in the dark, I have got a little routine thought out for you to test on her in the field. :
You meet up with the girl around class again, make sure she is isolated. Talk to her slowly, calmly but in an exciting manner.
You: Hey weirdest thing... you remember you told me about kissing girls?
HB LabBlower: yes...
You: well I was dreaming I was kissing a lot of girls, and you kept trying to steal them for me, don't you think that is weird?
HB LabBlower: haha yes, definitely
You: At the end I kissed 7 and you only 6 girls...
HB LabBlower: hmm okay weird, or blabla.
You: you were pretty angry and then you demanded a kiss from me and then I woke up. Weird huh? What could a dream like that mean?
Just look her in the eyes from there and see were it goes. She might think you are nuts, or she might think it is cute. This is not even a regular routine or something, just a weird story that you might use to show her you are an exciting person. (learn to speak in exciting fashion about yourself. The dream about kissing girls was YOUR dream AND THEREFOR AUTOMATICALLY VERY SPECIAL!!!.
9. Goodnight and good hunting from Amsterdam.
