[Kabeio]

was fukin hard to me

 

[Riviet]

Yeah, apparently it was quite difficult, especially the last few, the 4u was also very difficult, they're making it harder every year.

They're making it harder every year.

Just what I want to hear for next year... However I could do all but one part in Q1, and I could do a few of the other ones so shouldn't be that bad once I've learnt more information!

the first three questions are usually easy peasy stuff. It intensifies from there. When you get up to about q 9-10 or even q 8, some of the q 8s are hard, the difficulty is significant - this is because they need to distinguish between a band 5 and 6, I think. Q 10 is generally aimed at the ext 1 candidature - I couldn't do it, but then again I suck.

i dont think so,
they have made it easier (by ALOT) as time has past by...
there is some sort of pattern where every second year seems to be hard.

Eg, 2001, 2003, 2005.
so you will get the easy exam..

2002 was the easiest 4unit exam ever set basicly.
2004 wasn't far off 2002 in level of difficaulty.

but don't count on this. eg 2000 was fucking hard and that was in the "easy" line. that is: an even year = easy test.
