RIP School Survival Forums
August 2001 - June 2017

The School Survival Forums are permanently retired. If you need help with quitting school, unsupportive parents or anything else, there is a list of resources on the Help Page.

If you want to write about your experiences in school, you can write on our blog.

To everyone who joined these forums at some point, and got discouraged by the negativity and left after a while (or even got literally scared off): I'm sorry.

I wasn't good enough at encouraging people to be kinder, and removing people who refuse to be kind. Encouraging people is hard, and removing people creates conflict, and I hate conflict... so that's why I wasn't better at it.

I was a very, very sensitive teen. The atmosphere of this forum as it is now, if it had existed in 1996, would probably have upset me far more than it would have helped.

I can handle quite a lot of negativity and even abuse now, but that isn't the point. I want to help people. I want to help the people who need it the most, and I want to help people like the 1996 version of me.

I'm still figuring out the best way to do that, but as it is now, these forums are doing more harm than good, and I can't keep running them.

Thank you to the few people who have tried to understand my point of view so far. I really, really appreciate you guys. You are beautiful people.

Everyone else: If after everything I've said so far, you still don't understand my motivations, I think it's unlikely that you will. We're just too different. Maybe someday in the future it might make sense, but until then, there's no point in arguing about it. I don't have the time or the energy for arguing anymore. I will focus my time and energy on people who support me, and those who need help.

The forums are mostly read-only and are in a maintenance/testing phase, before being permanently archived. Please use this time to get the contact details of people you'd like to keep in touch with. My contact details are here.

Please do not make a mirror copy of the forums in their current state - things will still change, and some people have requested to be able to edit or delete some of their personal info.

Different types of reactions: help

Before I talk about my next problem, I would like to shout out to you all for helping me out with the balancing equations stuff. I really know how to do it now!

But anyway, I got more problems on my hands for my big chemistry test on Friday (in roughly 2 days!). I need help identifying different kinds of chemical reactions.

I know how to identify combination and decomposition reactions, because those are so easy. My main issue is identifying single-replacement, double-replacement, and combustion reactions. Do any of you have any good strategies for remembering? Thank you

Don't quote me, but I think I remember a tad about them.

Single-Replacement: Its something with 3 variables, like "AB+C=A+BC" or something like that.

Double-Replacement: Like single, but with 4 and you swap them. "AB+CD=AC+BC"

Combustion: I just remember this had always yields a water (H20) and a salt (whatever that is). Something to do with C02, I believe.

Again don't quote me on this I'm just typing this as fast as a can with about a minute (literally) in class left.

RE: Different types of reactions: help

Single replacement is where you only have to replace 1 thing on one side to balance it (replace isn't the best word for this IMO but you only do one thing)

Double replacement is where you change things on both sides.

Combustion always has energy in it and energy is always on the right (CO2 might be energy, but most likely your teacher will just write out the word energy)

The less you try to control things, the less you need to.

"free speech under the constitution only guarantees the government won't stop him saying it and does not guarantee his right to say things and have no consequences at all as a result. also i completely doubt that he is motivated solely by "i'm saying it because i can" and is probably motivated by a more shitheady motive like "i think it's funny to annoy people and Rustle Le Jimmies™ and is just hiding behind the first amendment to try to deflect any consequences or make you realize that being allowed to annoy people is a superior moral right. you can still disdain someone for doing things for dumbarse wankery purposes and you have evne more right to ban and insult them for it" ~Trar's friend about Potato.

Thanks for the diploma… can I have my childhood back?

I’d love to have a battle of wits with you… but I hate to fight the unarmed.
