Smile a lot, sit next to this guy and talk to him. If the guy smiles back at you and his body is turned to face you then you know he likes you. Invite him to a party and if he comes along then he likes you.You could also get one of your friends to ask him if he likes you. Then you will not lose face if he says no.

Let him know what?

You don´t have to tell him this in a oral way. You can show it to him in your behaviour. The body language is very important and if you don´t speak to him directly, its more important then the voice. If you often give him presents without any reasons and if you meet with him and his/your friends and you go together eat something and you ever want to sit beside him then he maybe get the idea that you like him.
