Isolating your TOI will help. Try to get them to come over to your house after school and hang out.
It's a bit harder at school (especially High School) because girls will always care about what their friends (and non-friends) think about her situation. Girls are willing to dump you because their friends don't approve. That's an example of High School behavior.
Because of this, girls will be less open to mutual affection in public on high school campus. This sucks for guys who are like me, because I have a rather unappologetic style with esculation. So the question then becomes how to esculate sexual tension without putting social pressure on the TOI.
Reading palms are a start. Implement a lot of kino, but make it seem organic. You don't want to have robotic movements or be stiff and then suddenly start touching, because they'll realize you're purposely applying kino, which works against you. It has to seem natural.
Putting your arm around her (like she's your little sister who you're trying to protect) is usually acceptable in high school and won't neccissarly imply interest. I did it to female friends all the time, when I had no interest at all.
To create sexual tension, you must get the idea of sex in her mind and get her to associate that with you. You could do that through kino, talking about sex, or simply talking about sexual things.
TIP: Don't be a class clown or somebody who just likes to be funny. They're fun to be around, but are not sexually attractive at all to women. Being laid back and calm will make you seem more sexual than somebody who runs around trying to grab attention with jokes.
Try being more laid back. Talk slower (with power) and move slower. Good body language can be sexually attractive with women.

Is that a joke? It's everywhere! More than half of everything taught is designed to raise her sexual attraction to you.
He's talking about sexual esculation, not the basics of attraction.
