What are some songs or something that are good to learn?

ok so i have been taking lessons for three months and i cant afford to take lessons for another month and i have only a couple of lessons left. and my guitar teacher told me to thing of anything i want to learn or practice so we can get in as much as possible. so i was wondering if anyone knew of any good rock songs that i should ask to learn so i can get in as much learning as possible.i like rock and metal,newer bands like breaking benjamin,disturbed,papa roach,etc. that sorta stuff,but it doesnt have to be by those bands.just anything that will help me learn the most.
