6 a*s and 1 a this year. :S i hate business studies so much and its tommorow ugh, alongside ICT theory just to make the day better. Cambridge never gets the dates right.

Me too :c lol I've got ICT tomorrow and It's driving me nuts
BUT no business studies to sugar coat the day :X3:

Good luck !

Something such called as " Cambridge " is basically the MAIN reason why I do have trust issues in this world...
They're basically a group of wicked creatures '-' that you can never trust..
It's like one day they lift your hopes up with a paper and the other day they make you just go down on a roller-coaster -.-

Best part is i didnt even study for ICT, not even one tad bit. But then again i actually never studied for ICT not even in the mocks or premocks, and i got decent grades in both its really easy you just need have the general idea of how everything works, like microprocessor , expert systems, data security and computer networks etc etc.. Anyways i probably wont study for ICT anytime soon because Business is throwing me into depression. Good Luck!

P.S.
I do hate Cambridge but after seeing some singaporean o level papers im glad im doing CIE. lol

HEY GUYS TODAY I WAS HAVING P62 CHEMISTRY IT WAS QUIET EASY
Would you mind discussing the answer to the question where they asked the effect of using a burette instead of measuring cylinder and using a 100cm3 colincal flask?

What was the answer to "What will the effect be if a 100cm3 conical flask is used instead of 250cm3"
And what was the answer to "what formed in the student's evaporating dish when she did the crystallization process incorrectly"
Oh and.. how many seconds did you get from the graph.. 100s or 110s?
Thanks.

I wrote that since the flask will have smaller height its would be easier to judge the end point of reaction,as visibility is effected by distance.
I wrote anhydrous salts in powder form
I actually got 104s :p
