Dear Nene,

i don't feel comfortable with your sentences, i hope you don't mind if i made some suggestions

"This semester i must progress"
i kind of understand your underline point, but it just doesn't sound right to me
how about " I have to (must) make some progress in this semester"

"Let us together," this is only half of the sentence
how about "Let us work hard together" or "Let us do this together"?
