给这个英文句子改错

i went through the test for many times but i can only answer three out of the twenty questions

为了和前半句时态要保持一致，所以最好用could,可能在中国教英语不太注重can的时态，但是老外对can的时态还是蛮重视的，three out of the twenty questions 有点拗口，改为three questions out of twenty就好了~一个句子里用太多the会让人觉得罗嗦~所以我建议。。。
I went through the test for many times,but I could only answer three questions out of twenty.
但如果要重写的话~
I went through the test for many times,but could only answer three questions out of twenty.

把out of后面的the去掉

几个里面的几个,直接有 three out of twenty就可以了
