A) Essay writing (I know you said this wasn't a topic about this, but here's just some general tips that apply regardless of what style your area prefers):
Honestly the only way to get better is to write... a lot. Personally I used to be the kinda person who got okay grades on essays, up until I had a teacher in middle school who made us write a short essay every single week of the entire year. I hate, hate,
hated it, but a few years later I looked back and realized that because of that I had actually become really good at writing essays (I made sure to send the teacher a thank you email, which I hope made up for how much of a horror I was in the class
). Writing, getting feedback, and practicing the skill of essay writing over and over is the only real way to get better. That said I can drop a few pieces of advice that I learned over my years of slavery in the world of essay writing.
1) Spell check/grammar check. If you're ever losing points on these than you have nobody but yourself to blame.
They exist, use them.
2) Think about what you are going to be writing about (and the argument you are going to be making, if one exists) before you ever set words to the page. Writing off the cuff works great in the world of creative writing, but an essay requires a little bit more structure. You should have at least the basic supporting points in your head by the time you write your first word, and now that you have the basic points down, you can use the opening paragraph to structure the order that you will address the points in.
3) Writing in big blocks. I know people who swear by writing a little bit every day, and it works great in more creative writing. But I'm not lying when I say that my smoothest, best-flowing, and highest-scoring essays had their first drafts written in a single 4-6 hour session. Small chunks get things done, but like a good conversation everything fits together the best if it happens together, rather than the first two sentences now and the next two a week from now.
4) That said, give yourself at
least three days to write an essay if you want the best work. Write the essay on day 1, then take day 2 off completely. Don't even think about the essay. Then on day 3 go back and read what you wrote. I guarantee that you will find things that don't sound their best.
5) If at all possible get someone to look at
your actual drafts (not just listen to your ideas) and give feedback on them before you turn them in. Ideally this should be the person grading it, but if you don't want to do that (or they don't want to give direct feedback), then any other person will work (though preferably it should be someone with fairly good essay writing or logic skills). Ask them to give you honest feedback about the parts that aren't working, and make sure to tell them that you promise that no matter what they say you won't be offended. In fact it might be worthwhile to actually ask them straight out what part of the essay they thought was the worst, because I can guarantee you that, like in reading it yourself two days after it's finished, there will always be something that they don't think is perfect.
B) Work Ethic:
Along with environment, honestly the only real good piece of advice I have for work ethics is to make things into habits by starting them, and ensuring that at least for the establishment period you don't give yourself any exceptions (after the establishment period I find the strategy that works best for me is to actually give myself X many "exception cards" for each habit, which I can spend to give myself an exception and that refresh yearly or quarterly). Of course the doing things regularly enough doesn't necessarily play that well with the writing in big chunks aspect from above, but it is possible to establish habits on a weekly basis (every tuesday is homework night, etc.) rather than a daily one. That said keep in mind that weekly habits will take much longer to establish before you can let yourself take a break. Daily habits can usually be established fairly firmly in as little as 3 weeks, but for a weekly habit you are probably going to need to hold yourself to the idea for at least a couple of months before you allow yourself to take a single exception from the habit.
C) Quotes:
Honestly I've never really liked quotes, and at least in my experience here in the southwestern US they are only really serious business in high school english. In college you are generally assumed to know when a quote would be helpful and when just the idea itself or a reference is going to be enough, so it's not as important to simply memorize quotes. That said here's the ways that I survived that period of time:
1) If you see a really good quote as you are reading then write it down with a note where it's from. In some more extreme cases you might want to actually consider memorizing the best few quotes dependent on your teacher; a memorized quote won't always be able to be used in every essay topic, but being able to whip out a good quote even without the book to reference is a sure-fire way to score big points with most english teachers when you get a topic that you
can use it on. (In that respect try to memorize quotes that fit a wide variety of topics and without overlap to get the best use out of them).
2) If you find that characters or the author is talking about a particular topic note down the topic and the current page number. If you find more dealing with the same topic, note those pages next to the topic as well. This means that when you need a quote addressing a particular topic you can quickly see a list of pages to skim through and find a good matching quote from, granting you a little bit more flexibility than #1 does (though requiring you, of course, to have the actual book at hand for reference).
3) In a worst case scenario you can always skim the source for quotes to find one that matches your topic. This doesn't work as well with quotes from literature (a 500-page book is not a fast thing to "skim" without something to help you like #2), but it works great with research papers where you have a larger number of smaller sources. Teachers always say that you should read the world and then write your paper based on what you find, and that's certainly the best way to actually construct your argument in the first place. However in terms of quotes/sources it's much, much easier to do the actual writing the other way around. Once you have done some basic reading to frame the argument the right way in your head, start to write the topic, then go and find sources that support what you want to say instead. Assuming you aren't crazy in your argument than there should be plenty sources out there that match your arguments already, and then you can just pick and choose the best of those to actually reference or quote as needed.
