Is anyone taking mitmath 6.S083 / 18.S190?

I am new to julia ecosystem.
I started using julia as a matlab alternative and because of it’s similarity to python(in syntax and practical application).
I am following mit’s 6.S083 / 18.S190 to learn julia and get familiar with it.
it’d be a lot of help if someone(who is also taking the same course) pointed me to the discussion forum for this course because, i’ve some questions regarding some course topics and homework assignments(i am stuck on 2nd homework problem)
