[Tirtho Sarker]

plz some quick guidelines about Q2

structures you should have idea about -monocot stem and root, dicot stem and root,trachea,bronchus,bronchiole(you can find these in google).....but draw only what you can see.
plan diagram means only layers.no need to draw cells.high power magnification means 45x lens.
also while drawing dont use broken lines,use share pencil.

Yes. First one was longer.. my results were not coming, so wrote estimated answers since theory and table part is mire important.. did all That.. I made A few mistakes... :'(

I cant say anything... I drew graph wrong and in first question, I gave estimated readings since my results were not coming... Didnt draw bar chart, drew curved graph...

What was the significant error?

you messed this one too? This paper was easy! :|

 

[Sheikh Nahiyan]

Okay... So the exam went pretty okayish...

Question 2 was easy to be honest. But I am confused about the comparison part. :|

Question 1 was easy as I didnt spend much time doing the experiment.. The latter part of question was best to be honest.. I guess I did all thing right in that part.. And as for the experiment, as the concentration increased, time decreased.

Paper was easy.. I didn't do that bad.. q2 was good. Did bar chart mistake, results I estimated..

Same here. In the end I just estimated results.. q2 was gooooddd.. but I didn't make bar chart, will I get marks for labelling graph? And significant error was? I wrote colorimeter should have been there for accurate judgement of colour, right? Secondly, variables immobilized - I wrote phy and temp, right?

Yes Q2 the practical part was easy , the questions weren't hat easy .. i hope i did them well though .. and yes the comparison was a bit confusing x_x
Q1 i messed up in one of the concentrations /: and the other questions i hope i wrote correct answers /: those theory-like questions scare me x_x
anyways .. lets hope the thresholds are as low was may/june 2013 or even lower :'o

 

[Rosy S]

Oh it's fine as long as you completed the questions... I had my milk solutions contaminated so I re-did my exp I couldn't estinate at all...

Yes. First one was longer.. my results were not coming, so wrote estimated answers since theory and table part is mire important.. did all That.. I made A few mistakes... :'(

Significant Error determination of end point / color change

You should have made the chart.. I dont know. They should give you 1mark for labelling the axes. Significant error in which one? Oh.. yeah.. those two? I gave error while preparing the different concentrations of the solutions.. And for the variables i wrote; use of a water bath to maintain temperature. use of buffer to maintain pH and another one i cant remember.. :\
