how to revise for biology ???

Ive just started AS biology (AQA) and in my GCSEs I revised for all the sciences with detailed revision cards but theres just so much content that i am doubting if this is an effective method anymore. How does everyone else revise for bio? Do you just write notes and learn everything from that?

I'm writing notes. then majorly condensing those notes down. like legit the MOST important things i highlight or whatever. I'm also doing questions by topic. you can easily find them on the internet. good luck. PM me if you need any bio help, I'm doing the same board as you

agh ok thanks for your help! Have you just started or are you in year 13? I'm super confused about hydrogen bonding so if you could help that would be so great

just started. finished biological molecules and food tests.

hydrogen bonding in what? cellulose?

at exactly the same stage! Got a test on wednesday on carbs and food tests so just doing some revision. and i understand about the hydrogen bonding in cellulose (adds strength, forms cross linkages between parallel beta glucose chains etc.) its just the first page in the text book says about polar molecules and the uneven distribution of charge when talking about hydrogen bonding which i don't really get but idk if its that important ??

i believe it's the structure of things like water which makes it polar. if you see a water molecule, there are two positively charged hydrogen ions bonded to a negatively charged oxygen atom. this means one side of the molecule is positively charged, and the other side is negatively charged. this makes water polar...

does this help.

because, having a hydrogen ion would make one part of the molecule slightly positively charged as hydrogen is a positively charged ion.

I've studied AQA biology AS and A2 and just came out with an A* this year. The best way I've always found is to keep reading your notes, as often as you can. While you learn new topics and do homework for them, take a few minutes to read over your notes on previous areas and make sure you still know your basic principles. Some of my close friends took biology with me and relied on cramming the entire course in the months before the final exams, coming out with Bs and Cs. Making notes on the entire course is just a waste of your time at A level, except for specific topics that you really struggle with.

Hope this helps!

Why is making notes on the entire course a waste of time? What would you do instead?

Yeah, I phrased it badly. Make plenty of notes in class, though don't waste time on further flash cards and revision notes for every topic you do. There's an insane amount of content, so it's a waste of time to rewrite notes you've already made for revision.

So revision for you would be just reading over your notes?

Normally, with help from textbook notes. If there are topics that are really hard to learn then resorting to flash cards or further notes is definitely okay. Ultimately, do whatever works for you though.

You'll get penalised in your exam if you say there are hydrogen ions in water. Water is a polar molecule consisting of atoms of hydrogen and oxygen. Hydrogen atoms have polar positive charge, while oxygen atoms have polar negative charge.

Nothing seems to be working for me though

I really don't know what does. I got a D in Biology..

It's so difficult revising for biology. Sometimes you just don't know how to answer the questions or what they are even asking for.
