Are my ways to summary my past achievements in 1 sentence correct?
A: I improved the understanding of my students.
B: Most student passed their exams
My past achievements included improved the understanding of my students and all student passed their exams.
My achievements included improving the understanding of my students and all student passing their exams.
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.
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.
