summer school????

i can't make up my mind. should i go for summer school or not? the university has agreed to waive my tuition fees for summer school. that cuts down my designated expenses by about half. i'll also get to do one german course during that time. which means, less modules for the proper semester. BUT! e accommodation still costs quite a bit. dad says finance part is ok. so what's stopping me? am i getting last min jitters? i can't decide!!!!!!! i'm gg craziieeeeeeeee
