As long as you dont sit in the corner, your bound to make friends. Like in some classes just make small talk, like even asking what there doing for there assignment or that looks like an inresting book whats it about. Even pairing up with someone new you didnt even think have the same intrests could turn out to be your best friend. Go to clubs that semi intrest you and might find people with the same intrests. Dont be afriend to stay behind at lunch to get help or finish work as it does help you in the long run and even could make you a new friend. Like this time in art class a few people needed/wanted more time to work on there work including me, we turned it into a friend club and place you didnt have to worry about being judged (it was called art club but we didnt do much other then goof off and hang out). We had pot lucks for christmas,end year, halloween...well when ever we could plan it realy (mostly junk food we brought in), teacher even bought us pizza once (one of the best teachers ever), we did scare other peopleaway who joined one day and never showed up again...we were weird and didnt care (well we only acted like that in that room .) teacher trusted us in the room alone if she was in the school.... because she wasnt allowed to let us in if she was out of the building so are club hanged out in the halls when are club got little to big forone table in the cafe..
Yep test schudles are plan werid like the teachers had a meeting to have all the tests the same day or week XD Never fall to far behind in work as it will be hard to catch up and bite you in the but later.
Also depends were you go to school how good the cafeteria food is. Mine was awsome all made fresh from the culinary. From cakes (cheese cake, chocolate cake and others), pudding/jellow/muse cups, salades (one with ham, beef, cheese, egg, and vinigrate sauce), chicken thingers with homemade honey dill sauce,chicken raps, burgers with bacon, pizza, suacey chicken nugget things, frys and potuine. umm cinimon buns, cheese buns, chicken burger, soups, cookies, and there was gourmet friday (old people come to eat there... )like fancy breads, fudge, octopuse and other stuff I cant name at the moment.
Me and my friend once sat at the back of the class room (till teachers swapped room part way into the semester) she said it was like being the main charater in an anime sitting at the back of the room next to a window... the new room didnt have a window sadly

we once saw a chicken in the parking lot or a realy fat/huge raven and we live in the city.. so no chickens here not even legal
Also if you get the chance do the 30 hour famine best time of your life. You hang out all night running around a locked school till 12 am (though you dont eat you drink soo much juice you have suger energy) then at least at my school the janiotor takes you on a tour about old things about the school and ghost stories and rumours. Then your stuck in a smaller area like the gym or somthing as then only one teacher or two is on duty unless need to go change/us washroom then you get to leave.you could ethier play cards, read, watch movies on lap top, talk or sleep then get breakfist made in the mourning.
So try new things, keep up your studing as its what counts towards your career, and have fun/hang with people you like and it will be some of your best years
