Wow, it was easy

 

[Emily793]

yup was easy except for the slide drawing part im unsure if my drawing is appropriate!!

 

[rahultaneja2010]

anyone wanna discuss 35 with me ?

 

[mrpaudel]

well....paper was so easy..!!..xcept the slide one..yeah as emily793 said..!!

 

[rahultaneja2010]

r u guys talkin about 35 ?

 

[mrpaudel]

m talking bout p33

 

[Emily793]

p33 too!! mrpaudel how did you draw it?? i cant wait for 24hr hours want to discuss the paper with you guys!!

 

[nano9595]

i did p33 too it was easy but i cant help feeling that i messed up some question :fool:
i just hope that im wrong

anyways i ll just have to wait till after the 24 hrs to know

 

[panda222]

Ok...paper 35 was super hard. I could write an essay on that.

Couldn't think of the 2nd improvement so i just put town "rewrite instructions". lol

 

[mrpaudel]

though 24 hrs is not over.2 3 hours to go..!! i think its not against the rule of XPF......p33 all over the world for bio is over till now...so..

@emily793: well...left a space for darkly stained layer, and..made two layers above it as i saw there were two layers when i magnified...!! and...made a single layer..i kinda see some projections in the lower layer( well this is what i see, it may not b projections) ...so made a single layer down..!! and....that is what i made...!! but i think..i should have made other layer down that one..!! but i didnot...!!.

and what about the nucleus one? and labelling..nucleolus..that was so difficult for me..!! i wonder if i can get max of 3 or not..in that figure..!!

 

[nano9595]

^^^ yeah i drew it just like u but i drew a second layer
about labeling the nucleolus it was difficult for me although all my friends agreed that it was the easiest part of the exam

i think ill lose about 2-3 marks in that paper is that good?

 

[paridhi shobhana]

i think u wud be getting an A inshallah if u r only losing 2 or 3 marks becoz ma teachers expects grade thershold is about 30 as A !!! nd wat did u ppl get for the uncertainity in the paper :/

 

[Emily793]

was uncertainity 6.7% and concentration of U between 0.5% and 0.05% guys??

 

[paridhi shobhana]

my uncertainity is definetly wrong i might only get marks for working nd ya the conc of U was 0.5

 

[Emily793]

im losing marks for my drawing...

 

[paridhi shobhana]

wat was ur x and y axis ??? time in X and the conc in y ryt

 

[nano9595]

 

[M95Caire]

wat was ur x and y axis ??? time in X and the conc in y ryt

Yess changing the time was the independant variable so it propably should be on the x-axis !

 

[M95Caire]

my drawing is wrong too emily

and my teacher said that the percentage error is 3.33%

and i ve got the U between 5% and 50% and my friends got it between 5% and 0.5% but my teacher said
the examiner will not deduct marks as the conc of U depends on what u ve written in the table

I got the answer 3.33 too, but I just wrote "3" i think they will defintly deduct marks for this!

 

[Emily793]

Are'nt we suposed to do 1/15 for error? Since we are recording time twice??
What differences did u put guys? I put projections one was circular shape and the other rectangular. Fig 2.2 was larger in size, and the layer y or x dnt remember what i wrote was thicker in 2.2, there was also taste buds in 2.2 and nt 2.3
