She succeeded in all major courses and won the outstanding student award and the college scholarship.
这个句子这样写没有语法错误,第一个and连接两个并列谓语succeeded与won;第二个and连接两个宾语一起放在won后面;
如果你想让句子语法正确又有突出谓语而不重复用词,可以这样:She succeeded in all major courses and won the outstanding student award as well as the college scholarship.(其中as well as是"及"的意思,可以连接两个并列成分)
