[ Block 1 ] [ Block 2 ] [ Block 3 ] [ Block 4 ] [ Block 5 ] [ Block 6 ] [ Block 7 ] [ Block 9 ]
26th May
I actually finished this block some weeks ago (slow in catching up with these webpages). I thought it was better than Block 6, but that was only because of the Organic Chemistry, which is much more straightforward than the other stuff! I have a few problems with pharmaceuticals though, so hopefully that won't crop up all the much in the future! TMA06 just needs a tiny bit of tinkering to the last question and then it will be ready to go. (I have to admit though, that I've forgotten half of this block already ... )
27th March 2003
I've just turned to the opening page of this block. Can't wait to get into it! :) There is absolutely plenty of time though, as the next lot of materials don't get sent out until May. Good job too, by the look of it! (By the way, this is the worst book cover so far!)
