My past achievements include(d) A and B

[uktous]

Hi,


Qesution:
Are my ways to summary my past achievements in 1 sentence correct?


Past achievements:
A: I improved the understanding of my students.
B: Most student passed their exams



Sentence1:
My past achievements included improved the understanding of my students and all student passed their exams.
Sentence2:
My achievements included improving the understanding of my students and all student passing their exams.






My opinions:
The main point how to write achievement A and B into nouns.
I think sentence 2 is better because I write 2 achievement into nouns.
However, I am describing the acheivement in the past, not now. So sentence 1 seems to be more grammatically correct.



Thanks

My past achievements include improving the understanding of my students and having all students pass their exams.

But if your actual achievement is: "B: Most student passed their exams" and you write "all student passed their exams", then you are lying.
