59/60?

 

[meeeeoowww]

i suppose no 1 in dx world will score full marks in the last question!!n evry1s answers will b wrong coz it was meant to b only for d einstein's generation to solve!!!

It was easy :O

 

[meeeeoowww]

really dn tell all ur answers an ill mail it to the examiner as their mark scheme for reference.....by d way congrats i suppose dn ur gonna top in chemistry coz all d brightest students got it wrong... imanmalik

The last question was messed up yes, and I lost a 2-3 marks here and there. So say in total 7-8 marks out the window. Hope the prctical goes well

In last question i guess i loose only one mark for the part in which we had to write the structural formula of organic product formed when it reacted with fehlings reagent!!i will loose marks in purity i think 2-3 marks wbu all?

 

[meeeeoowww]

i bet d threshold for dx paper will be 52-51/60 for an A...

 

[imanmalik]

lol i forgot a number in one of my calculations and LOL I THOUGHT IT was Br2. Okay so i think i will loose around3-5 marks.

no it won't be that high max mark for A would be 46-47 and minimum mark would for A would be 43-44

​

mayb yea coz almost all d ppl at my centre are definitely goin to lose 10 marks here n dere for sure.....was the enthalpy value cumin in -47 or someting?buh it sure was exothermic reaction....most of d ppl evn went wrong on d 2nd question based on moles...

it was easier than i expected save the last question

90.8 if you've rounded your previous answer (which they expect you to do...).

 

[meeeeoowww]

i suppose d percentage purity is in 90s value coz mny ppl got it 90%...

Am I the only one who found that question easy? Everyone at my center was whining about that question too. :S

Oh well. I'm expecting the GT to be VERY high - 52 at least.
