Damn I need As if I want a B. :eek:

Nah you don't. 305 is 25 points higher than you need to get a B.
If you want a B you need 280 UMS. So if you've already got your 75 in your coursework and a 60 C today you need to find another 145 points somewhere. Two low Bs would do it by the skin of your teeth. Or even a high C (69) and a medium B (76).

The question wasn't about rats. It was part of the alcohol one. Scientists make a drug to treat alcoholism / addiction. They test it on drunk rats first (efficacy). They didn't ask you about the animals at all so if you skim read it you might have missed it.

They asked for an animal and I put fresh water invertebrates (had no clue you had to specify?) as it says in the AQA text book, would this be wrong?

That's right, and you don't have to specify. Just lots of people did because they learned them. Invertebrates is fine.

What did people get for the question about all boys drinking and why was the hypothesis not valid??

i said they only tested 15 year olds so other ages may not drink alcohol

This hasn't got much to do with this exam but why is a response from the brain quicker than the response through the spine. I automatically placed spine as the fastest response as when you have a reflex, it does not go to the brain but through the spine with the relay neurone (I know I was wrong but just want to understand why)
