I've repeatedly failed algebra 2.
I really need to pass it, I have a month before the class even starts.
I want to get a head start on this class, someone recommend me what to do.

I go to a sub par/ cheap as hell school, so we are pretty much required to teach ourselves, and the teachers take a back seat approach to everything.

2nd'ing and 3rd'ing. I've seen it happen already where people try to bring down this site and its author in terms of quality, but... give me a fucking break. This is one of the most powerful sources for understanding mathematics.

This, seriously. I went back to college recently after 15 years of being out of HS and I owe my ability to actually pass to this site.

It is of help for first year undergrad university courses actually. You should be able to learn from a textbook past that anyway.

same anon who posted the link, I hear what you say so far I have taken linear algebra and calc2 but when I have to take advanced classes like discrete mathematics and other high level classes I will have to relay on some other source maybe MIT opencoursware and such.

Well, then compared to nothing, the Khan Academy is better for understanding mathematics, but not the best. That is essentially your point.

KA is terrible for anyone wanting to major in math, then again he is an engineer IIRC .. and the practice problems are a bit too easy IMO

I find PatrickJMT to be a better lecturer but he has no problem sets

tl;dr never pigeonhole yourself by using one site

>> No.4637918

>>4637852

I'm actually curious as to what parts of the Early Calculus and Linear Algebra sections you find lacking? Unless those aren't considered college mathematics.

Hell even their non-mathematics sections excel. I remember introducing the site to some friends of mine taking organic chemistry, and there was a significant increase in their grades after that point.

Because even the most basic lesson are better than no lessons at all.

Basically, if I am not being subtle enough.... Post some alternatives to Khan Academy and we will be happy to use them.

>> No.4637924

>>4637917

I've seen PatrickJMT always brought up as a better math teaching alternative to Khan, but their reasoning behind it is usually "just because he explains it better". I'm really curious as to what makes him a better tutor, not for the sake of finding out whom among them is better, but to find out what people respond to most in a tutor (for future purposes).

If your options are Swahili or nothing, it is better to take Swahili because at least you can learn the basics of language to eventually learn English.

Like I said, he is a better lecturer. He speaks more clearly, stutters less, stays on track, has no interruptions like his wife coming home from grocery shopping (this has happened in one KA video I've viewed).

He gets his point across adequately without rehashing and repeating himself over and over. This I think is a gift that the best math teachers have. Some don't explain well enough for their entire class, but some just love to hear themselves ramble.
