I'm happy to report success on the Delta Module 3 (big paper). I got the middle grade, not the highest, but higher than just the basic pass, so take my advice for what it's worth. Admittedly, I didn't put as much effort into it as I could of and just kind of sent it in at the end, even though I know I could have worked on it more and gotten the higher grade. Anyway, my tips:
1. Get yourself into a good preparation program (The Distance Delta) and then follow ALL your tutor's advice.
2. Follow ALL your tutor's advice!!!
3. Not that you'd want to pick an "easy" specialization just because it's easy, but if you're doing any exam preparation classes that semester, "examination preparation" is a good choice because it's relatively easy to do assessment of your students and there's a lot of materials out there to read and reference. Plus, it lends itself to quantitative measurements, which could be quite helpful.
4. Unlike Module 1, where studying everyday is the key, this took more focused effort. I set aside a block of about 4-5 hours each week on my day off and that was sufficient. It would have been confusing to try and do 20 minutes/day or something like that.
