It is quite normal, however being an instructor myself the fact your course instructors aren't approachable
isn't very good and this must make the course even harder!
As instructors we aren't here to catch you out, however we have to ensure you know your stuff before you are let loose online!
The other thing is, if you aren't happy LEAVE! Granted the grass isn't always greener but it is pointless being unhappy!
Just my opinion!

p.s good luck to you if you stay.
