I have heard of a number of tutors going there to watch the
students do work only (just find worksheets, bring over see student
do). These tutors also not very sure how to do one.
Just like financial planners, they might even be confused with
what they are selling. I have had one trying to sell me Indian
equity fund, saying it will rise soon because it has dropped a lot.
And when I did my own checks, I saw that it has reached a double
top and is going to fall. Really did fall -.-"
Enron dropped a lot too last time.
And everybody kept buying because it looked cheap.
