Students: We have free audio pronunciation exercises.

Us and we are both 1st person pronouns. Let ‘us’ is correct.

Let “us”

I know the 'us' and 'we'. Like a 28-year-old said ”let we go”.

Teachers: We supply a list of EFL job vacancies

Let we go! is wrong.

Say Let us go! which abbreviates to Let's go!
