Okay, hopefully. Thank you.

but I don't do Irish so I have almost all of tomorrow and Tuesday morning. I just hope it comes back. and I hope it's a kind paper. Btw, is it on the syllabus that there'll be 1 long ques from unit 1, 2 from unit 2 and 3 from unit 3 or can they put in as many from any unit as they like? 
I'm not sure if its on the syllabus but its always been 1 ecology, 1 genetics, half or 1 on photosynthesis or respiration and half or one on plant or human reproduction, and the rest from anywhere. They could change that though I think.
If you're really stuck, cover:
Food (short q)
Ecology
Genetics
Reproduction
Photosynthesis/respiration
Experiments(esp enzymes, alcohol)
That will get you more than half the paper.0 -

thanks a million. I have everything you have mentioned covered, + unit 2 and experimrents and a good bit of unit 3 too but it's mainly the plants that I can't get my head around. 
hopefully I'll have enough choice. Fingers crossed,.... 0 -
Despite trying to get my head round those Punnett Squares or whatever they're called, I just can't. Can anyone explain them it's not too difficult? Thanks in advance.
Same here. I spent ages reading over the theory tryign to understand it, and that's fine. But when it comes to an exam Q I'm hopeless. Iv'e given up. 0 -
Is there any bit in particular you cannot get your head around? Is it trying to understand what to put in the square, or doing the square itself?Same here. I spent ages reading over the theory tryign to understand it, and that's fine. But when it comes to an exam Q I'm hopeless. Iv'e given up.0 -

Its the linked or sex linked ones mainly.
And chromosome diagrams.
Any help much appreciated!
I have to study Irish now, but I will check up on this later. Thank you. 0 -

If I where just to look over all this would I pass the paper? Im really worried because I haven't really studied yet and I just about passed it in the mocks

Last year, the sections outlined were worth 270 marks if you chose to do them all. Now assuming you get say 75% of that stuff right, plus 25% of the rest of the paper right, you would get 58.75%.
Now obviously thats hypothetical, it could be worth less or more than 270 marks and you would prob get more than 25% of the rest of the stuff right if you just attended classes over the last 2 years!
So realistically it should get you at least a pass!0 -

Genetics is really easy man, it's just a simple little formula. Do it. Easy marks!johnson901 wrote: »Would i be safe leaving out studying DNA and genetics? Does it always come up as only one question on the paper and possibly short questions? Reallly hate it0
