Ended up re-scheduling last weekend following some dismal test marks after covering the relevant chapters on Security. Have spent last week covering Services, Threading, Application Domains, Configuration, and the weekend covering Debugging, Tracing, Event Logging, COM interop and Reflection.
Have taken most of the MeasureUp tests now, all without reference to materials. When I've been thorough things have gone OK (high 70%s), blotting the copybook have been Security (sub 40%) and COM Interop / Reflection (50%). The main thing now is concentrating on review of the test exam questions. Reviewing areas I haven't looked at for ages i.e. Collections, Generics, Eventing. Areas that have received minimal attention are not going to be revisited now (i.e. Regular Expressions, Graphics)
I've got a couple of spare hours in the morning and then exam is mid-afternoon. I'm feeling that I'm not quite as solid as I'd like to be but it is definitely worth a shot now.
