AQA Biology Unit 2 with Anon_98.

Variation exists between members of a species.
The need for random sampling, and the importance of chance in contributing to differences between samples.
The concept of normal distribution about a mean. Understanding mean and standard deviation as measures of variation within a sample.
Candidates will not be required to calculate standard deviation in questions on written papers.

its tomorrow?... my ones on Friday i do AQA B2

Similarities and differences between individuals within a species may be the result of genetic factors, differences in environmental factors, or a combination of both.

The double-helix structure of DNA, enabling it to act as a stable information-carrying molecule, in terms of:
•the components of DNA nucleotides:deoxyribose,phosphate and the bases adenine, cytosine, guanine and thymine
• two sugar-phosphate backbones held together by hydrogen bonds between base pairs
• specific base pairing.

does it look like i posted in the gcse forum?

Uh that took me quite long. Well, I've just finished writing out my notes and now I'm going to try and memorise them.

Hey anon, why don't you use the power points available online for aqa. I used them for a2 and think they will help you understand the information quickly (its easy to go through them) plus they have used info from nelson thornes. Try that out. And im retaking too tomorrow so if you need any help let me know! 😊

Yeah it seemed like it, should of been more specific

Powerpoints? Do you mean on 'get revising' or..?

I feel like I can only really learn/memorise stuff when I make it myself tbh but alright, I'll try- Is there any chance you could direct me to the source?

+ thank you.

Alright, I'm making this thread bc I haven't revised for tomorrow's exam. I thought it was on Friday so I was going to give myself these next 4 days to focus on it but it's not on Friday which means I have today to try and revise as much as I can.

Yes, I know I should've probably done it earlier anyway but I didn't/couldn't so that's that.

I haven't memorized this unit since last year. I've got some notes from when I did it at AS + also some from March/something but that was ages ago so I've forgotten what I even did + nowhere near enough anyway.

Whatever, it feels like I'm more/less starting this stupid thing from scratch and I've wasted all morning/afternoon staring at my books bc I'm feeling really overwhelmed so I'm hoping this thread will help me bc it's the only option I have left.

So, blah I've got 28 topics to cover + quite a lot of past papers to do and I've got around 18hrs to do it.

I feel like I'm going to vomit.

Anyone is welcome to post stuff here if they're also doing a particular topic at the same time as me but please don't post random information about random topics if they don't align with what I'm doing bc I'll get confused.

Anyway. - I'm going to be posting all the revision stuff I manage to do to help keep me motivated.

You're welcome

Good luck

Are you sure your exam is tomorrow?

I do AQA Additional Science B2 Biology, and my exam timetable states the exam is on Friday 10th June.
