The TSFX

Na it wasn't hard.

But you have to understand. For me first one and hadn't even done reaction pathways >.<

Ohh so you're doing year 11, are you one of those who do year 12 subjects on top of everything?

lol martoman, ur not asian, but ">.<" IS just so asian it makes me laugh XD.
don't worry ur the genius one remember. I support Maos nomination of u as Mod!
And is tsfx really worth doing sometimes?

I don't see what was so bad about neap 2010 :S. I got lucky on a few questions though.

keep in mind that neap was one of the first exams that many people sat, it wa my first and I wasn't finished the course yet either, on top of that time management was tough (first exam taking it slow getting a feel for it)

tsfx has some questions that would really catch you off guard if you didn't know the syllabus like the back of your hand, so I'd suggest it.

The one I think is the hardest one I've come across is this KBT lectures one... geez looks daunting.

Yeah i'm one of *those* kids who didn't do 1-2 chem. *sigh* sometimes I feel like i'm missing out.

KBT looked challenging, but, honestly, not impossible. Lots of long questions though...

[iffets12345]

KBT?

[Greggler]

neap 2010 had a crapload of explain stuff too which wasnt too hard.

but for people who hadnt finished the coursework it probs would have been a bitch

Lol when it asked me to find the mol of electrons that were involved in the reaction that formed the
Cr3+, I died a little inside.

KBT?

Here. A free exam from a lecture organisation three 99.95s from last year organised.

It's definitely the hardest one I've seen yet. And the answers go into much detail so I'd recommend this test as the last one you attempt.

[stonecold]

Easily the hardest exam is KBT.  A little unrealistic, with the electrons question, the electrical conductivity question, and VCAA would at most, although highly unlikely, get us to draw ONE nucleotide, at best.

I doubt it would even happen though, as the examiners have to mark it somehow...

The chromatography question went on forever also, and it was difficult to count the NMR splits, which in the end you didn't really have to worry about.

Also, can anyone explain the solubilities of glycogen, starch and cellulose?

I get that:
glycogen = highly branched
starch = branched
cellulose = unbranched

[m@tty]

Cellulose is insoluble in water because of its tightly packed structure.

I think the other two are soluble, though gylcogen moreso than starch.
