请教有经验的同学，关于上次拒签的解释

tarot2005UID: 2701698

上次去北京美使馆是两年前，因为要去旅游所以申请的B2签证，但是杯具的被拒，然后时隔一个月再次去签（因为当时特别想去美国玩），同样杯具，拒签。

今年申请了2015年秋的MBA，学校是个Top140 的学校，打算4月份去签证。 担心被问到为什么之前会被拒签，所以要准备说辞来解释。请各位大神和有经验的同学帮我出出主意，应该怎么解释才好。

我之前想了一个解释，贴在下面，请大家给看看，指点指点。
In the year before last, I applied for B2 visa. The visa officer refused me. I think that’s because I did not express my purpose very well to make officer misunderstand and also I prepare lots documents to support my purpose but I did not show them to the officer on time. But this time, I have big change that I apply for F-1 visa because I want to pursue 2-year MBA program in XX大学, that’s because after 3 years working experience I want learning more professional knowledge and polish my problem-solving skills in order to make a good life condition and big business career after back to china.

可能有点长了，请大家帮忙看看，不胜感激！
