This is fine; kind of formal, but it is grammatically correct.

Answer 3

There's too many commas. It should read "I suggest you take my demo class to see my effective teaching skills, which is free of cost"

Lmao 2 thumbs down? Must be from illiterate people. Trust the person who studied in good schools in Ct

Answer 4

It’s almost correct but expect that  After the word cost there is just one extra comma I would remove that it’s unnecessary 

Otherwise than the extra comma everything else it’s correct
