A few resources are worth mentioning annually here to introduce
them to new readers. Khan Academy
is one of those resources. Over 3,400 free
tutorial videos are there where you can learn a variety of subjects, from algebra to chemistry to American
history. At the first sign of academic
confusion, don’t have your parents hire a tutor. First, spend 20-30 minutes on the Khan Academy
and see if Sal’s explanation clears it up.
If that doesn’t work, then visit your teacher. Live help might be the best kind. But your teacher can’t help you with trig at
10:30 p.m. on a Tuesday like Sal’s videos can.
