Since I don't know your specific situation, I could be completely misinterpreting what you mean. But it seems you have 0% "figure out the problem".

Yeah, you're off. Really, my solve rate was darn near 100%, but I hit the occasional spot where I was asking 'what the hell are they looking for me to produce?' - and the answer wasn't in the book.

I wasn't counting the problems where I already knew what to do, or could figure it out without outside assistance. That's practice, not learning. Of my learning, IE learning the symbols, the properties of various constants and such, the execution of various rules*, that was done as I said - mostly NOT using the book.

*Not enough time in the tests to re-derive them, had to memorize

Like I said, I could be completely misreading your situation, but from what you wrote, it sounds like if there isn't a template for how to solve every single problem type that you give up.

I'd hardly call what I did 'giving up'. I would work a problem until I not only had it solved, but I understood the solving method. It must of worked, seeing as how I pulled an A in a class where 90% of my grade was from closed book tests.

Can you self-publish and get any respect from college book departments? Professors might be fairly easy, but getting the okay from your department to use a non-certified publisher/reviewed book might be difficult. Can you sell enough in order to justify printing sufficient quantities such that printing costs alone don't swamp most of the price difference?

It's not easy. Especially if he was under contract with the publisher for it and they pulled some shenanigans in order to raise the price.

That being said, I'd love to pull in some charity minded professionals to write and deliberately open source sets of textbooks.

It's pissing me and the students off because they really do need to have a text.

How long is this going to be true with resources like Khan Academy, Purple math, and everything else out there?

I am currently pissed at my calculus text(Larson/Edwards 5thEd ETC). While I read the chapters, more than half the book is actually just problems to work out, and worse, the methods to solve said problems are often not in the text. So I'd place my actual learning at about 10% textbook(and I'm being generous), 30% lecture, 20% math tutoring/TA help, 40% internet.

When the teacher is assigning roughly 1/10th of the problems as homework in a manner that often resembles 'this looks good, I like this one', etc... It should be trivial for him to do up said problems on a handout. Well, I'd recommend he make the problems up himself, but you should get the point.

How about I prove you wrong in such an embarrassing way that you will have to eat your words? I have that account because at some point I bought Rogers Internet service, and email was part of what I was buying in the package. Eventually Rogers outsourced their email to Yahoo!, so I have an email account that is paid for and that I never imagined would be handled by Yahoo! I am actually a paying customer, you dumb shit.

Also, Colorado should (if they don't already) have laws preventing the export of marijuana to other states where it is illegal. Want to grow for distribution in Colorado? Fine. Want to grow in the safety of Colorado to go profiteer in Nebraska? Jail.

I'm not a lawyer, but I think that would actually be illegal under the constitution. The states aren't allowed to get into trade wars with each other with prohibitions, taxes, duties, and such.

Yes, I know in this case that Nebraska doesn't want the stuff, but it's free to pass a general prohibition, it's not allowed to ban only weed from Colorado. Colorado isn't allowed to ban weed to Nebraska.

I think the difference here is that marijuana is illegal under federal law. It is not a law the states created, and so they are complaining about the disproportionate burden placed on them.

There's a really simple solution here: Do basically what Colorado did, and tell the feds that if they want to prohibit weed they can do it themselves.

but in practice, prohibitions against alcohol work just as well as prohibitions against pot - ie, not at all.

You want 'effective' dry counties, look towards Alaska. There are places that are pretty much only accessible by plane, and they have officers there that are almost like customs. They still get alcohol in there, but it's at a lot lower rate.

Down south, the only reason most counties are still 'dry' is a combination of:
1. Cronyism - the politicians are relatives/part owners of the alcohol stores located just outside of their jurisdiction
2. Temperance types - MAD types that are against any alcohol
3. NIMBY types - they're convinced that any change would be bad and that a liquor store would set up right next to them and draw drunks from counties over to their door step(despite the fact that the only reason they see lots of drunks at the store the next county over is all the people migrating from their county PLUS the drunks in the county the store is located in).

They bring so much that it's obvious that it's for sale.

And how much would that be? I know that federal statutes have rules in them where if you have more then X amount it's 'obvious' you intended to sell them, then lowered said amounts because the dealers simply started carrying less, stashing their stuff in small amounts. The only ones with large amounts were the mules. There are recorded cases of tolerant people where a week's worth of their habit busted those limits easily.

If you're an individual user driving the 200 miles from Denver to Scottsbluff, or the roughly 500 miles from Denver to Lincoln or Omaha, how much are you going to buy? Enough for a weekend, week, or are you going to consider buy months worth?

That being said, I'd rather see small scale dealers buying from Colorado than large scale drug gangs bringing it up from Mexico.

but it will be less if Nebraska and Oklahoma also legalise it.

I think of it like red light cameras, the 2nd invasion of Iraq, and most political campaigns - the justification they will give for the action isn't necessarily their justification, but the justification they think YOU will care most about.

IE for red light cameras they'll advertise on safety, but to most planning boards they're trying to sell them to they'll talk revenue. Bush wanted to finish daddy's war, but talked chemical weapons to the world for allied assistance.
