You don't want to cold approach relentlessly around school.

You want to work on building yourself into an attractive, well rounded man. Prioritize good grades, and your passions. Then getting laid after that.

You want to work on being sexy, being a good conversationalist, having a life, and reading signs of interest off of girls.

Here's a quick overview checklist for those elements, with a cuple game tips sprinkled in:

Being Sexy:

  • Get ripped
  • Step your fashion and grooming game to stand out among all the guys in a handsome, masculine way.
  • Work on body language to have a strong but not hostile presence

Being a good conversationalist:

  • Genuinely care about how people are doing, listen and watch closely.
  • Take the most intriguing detail of what she just said and use it to make a question/assumption. Example: Her Today I gotta walk my dog, finish this paper, go to practice. You: "What kind of dog is it? I can see you with a yorkshire or something in a purse"
  • If something funny runs through your head, just say it. amuse yourself.

Have a life:

  • Make plans and invite people along. "Imma see Rouge One thursday with X, you wanna come."
  • Make a goal to only be in your bed for sex and sleep, not reddit browsing and texting.
  • Try something that's out of your comfort zone, that doesn't seem you.

Reading signs of interest:

  • Look at what women do, not what they say when evaluating her attitudes toward you.
  • Watch while you talk to a girl for her: Quickly sweeping the floor with her eyes (looking down and away) after eye contact, putting anything on her lips/in mouth, playing with her hair, fixing something about her appearance, changing her pose/body language after she knows your around, holding extended eye contact, getting unnecessarily close when she talks to you or walks past you, leaning towards you, asking you questions about yourself, having an attitude that challenges your ego.
  • If you see any of the above, tell yourself she wants to fuck. That she wants your dick in her mouth. Whatever you need to flirt confidently.

If you apply yourself diligently to things like that, prioritize school, and are honest with yourself (no ego about ability with girls)... you could be way better by the end possibly just one semester.
