I had gain good mard in all practice course by my work hard

I had gained good marks in all practice courses by my hard work.
gain---gained 因为这里的时态是过去完成时，had 后的动词用过去分词。
mard---marks marks “成绩”，它是可数的名词
course---courses course “课程” ，它也是可数名词
work hard---hard work work 在这里是名词词性，因为它做by 的宾语

考过去完成时态的句子吧
had gain 改成 had gained 就好了。

I have gained good marks in all practice courses by my hard work.

I had (gained) good (marks) in all practice (courses)by my (hard-working).

I had (gained) good (marks) in all practice course by my (hard-working).

I had gained good marks in all practice course by my hard-working
