5th June
I finished the TMA yesterday and am quite happy with it (it's not perfect!). As there were no questions on glucose oxidation or DNA (well, very little), I've an inking that those might crop up in the ECA. Anyway, onwards to Block 10 and the geology and palaeo! Time to let those little critters out of the box!
26th May
I bought this block, directly from the OU, about a month ago, as I couldn't sit around any longer with no work to do (the 3rd mailing has gone out - but I haven't yet received mine). Anyway, the printing of this book was all scew-whiff - but I still enjoyed it very much. There were some very complicated goings on with the glucose oxidation - but, all in all, I did enjoy this block immensely, especially the sections on DNA. I can't quite say I've finished it totally, as I need to do the cd-rom activities, when the mailing arrives - and, of course, the TMA.
