Difference between "seems like, as if, appears to be"

[Adonistalavera]

Greetings to all members:
How to use the following Phrases (Differentiates).
For example:
" It seems like they are having a trouble to take the exam."
" The Questionaires appear to be difficult why most of the students are having trouble to take the exam.
" As if the students don't want to take the exam because the questionaires were so difficult.
I need your comments fellow members. Please, correct me if they aren't in the proper grammar.
Thank you for your immediate response. :roll:
