your idear is strange~~~
do you know that as a secondary school student, if an ESL student (international student)has not been here for four years ( depends what university you wanna go, like OU, 3 years, McGill, 5 years), you have to pass TOEFL before you are accepted by universities, and if you want to stay at high school only for one year, are you sure you'd like to study 3 or 4 English books during a year?? are you sure?? it might not be a good idea~~
