Exponents SUCK! >_<; Khan Academy Milestone
For some reason, when I was brushing up on exponents, although I COMPLETELY understood the syntax of the function, I simply wasn't getting the the right answers on the practice test on Khan Academy.
I did SO badly, in fact, that my first attempt scored me a 43%!!!
How awful!
My second attempt
I did it again and -- for some reason -- this happened:
Again, I know this must seem like baby work to most of you, but for me -- a dude who's been doing manual labor since the age of 15 -- getting back to this stuff after half a lifetime away from it is a BIG DEAL.
And I wasn't even good at math in school, anyway.
... not that I was good at anything in school, but I digress.
Is this kind of hackerrank?
Proud of this guy salman khan founder of khan academy. His origin is from my country Bangladesh. :) :)
Have you tried freecodecamp? if you havnt yet then you can give it a try!
Khan is an amazing man and the originator of the notion of a profitable but free quality education system. This, honestly, is where I see the future of education going, because public schools are absolute horseshit and private schools are too expensive.
I haven't used freecodecamp yet. So far it's just been Khan and Codecademy, which has been amazing!
With the large of amount of choices for (math) education, many can have access to quality education without getting hit big on the wallet.
One problem I see is the "paradox of choice" situation where you wonder which ones are good and which ones are not.
Pluralism on the Internet has a tendency to shake itself out over a few years. There used to be hundreds of email services. Now, people only use a handful of known reputable ones. This will shake out in not too long of a time.
