Step 1: On the first day of class, sit in the back of class so you can see everyone. Arrive 10 minutes early to ensure you sit in the back.
Step 2: Get out a piece of paper. As the teacher is taking roll, write down the names of all the hot grils in the class. This is easy since all the hot grils will say "here" when their name is called. Alternatively, if the names of the students in your class are posted online, use this. If there are no hot grils in the class, bang your head against the wall.
Step 3: After class, do a Facebook search on all the hot grils in your class. The reason you're doing this is because you're trying to determine whether this gril is single or not. You don't want to waste your time talking to a gril for a couple of months and then finally asking her out only for her to tell you she has a boyfriend.
Step 4: Wait until the third day of class. On the third day of class, sit by the hot gril who you know is single because you looked her up on Facebook. You don't have to talk to her that day but if you choose not to, then you have to talk to her the next time you two are in class.
Step 5: Now that you've chosen a gril to sit by, the next step is to strike up a conversation with her. Do this 5 minutes before class. Your opener should preferebly have something to do with the class. An easy one is to ask her about an upcoming assignment, or about upcoming homework. Once you've broken the ice, continue to talk to her and act interested until the start of class. After class, talk to her again. Leave together at the same time and talk to her as you two are walking out of the classroom and in the hallway. This is when you ask for her name, and then you say "i'm (your name) nice to meet you" Now you've made an impression on her.
Step 6: Continue to talk to her before and after class for the next couple of weeks. Try to find places in the school where she might be hanging out before class. For instance, if she sits in the lunchroom between classes you can sit down talk to her there for 10 minutes. Be sure to shift the topic away from class related discussions to personal discussions.
Step 7: After about a couple of weeks of talking to her, ask for her number or snapchat. Text her on the weekends. Ask her if she wants to get together at the school to study for an upcoming test.
Step 8: After you two have been talking for a month or two, ask her out on a date. If she says yes, then great! If she says no, don't take it personally. Just because you get rejected by a hot gril in class doesn't mean it has to be awkward.
