Actually, I think you are too young to think about the future which happen four years later. Just pay more attention on your daily study, and you will know if you have a good knowledge of mathmatics, you can study almost every subjuct such as economics, software engineer.The graate exam is, as far i am concerned, too difficult if you want to go to the top universities say Peking and Tsinghua, especially if you choose the major of economics, the competetion is much more acute than you can imagin. For example, I take part in the 2010 Graate exam to Renmin university. However it finally prove this is really a tragedy. But if you think you are good at English and math, you can try, while you don't have so much confidence, to choose a less great university is a realistic and better choice..看你的在哪所学校,如果你们系领导很重视考研,老师会给你上考研辅导课,我建议你还是去考数学专业方向的,这比较容易些。跨专业的呢还可以考管理,毕竟你的高数十优势。数学系考研的大多败在英语,所以希望你好好提高英语。
