Glad you got signed up with WOS, colcop.

. Good luck with it, and let us know how you get on with them. I was happy to pass on the info even though I missed out myself. As it turned out, I relocated and had to take 4 months out of study anyway, so the flexibility of Skillstrain is proving good for me in that respect. I'm flying along again now, almost halfway through.
Here's that link again for tippet:

(and I've just realised I've confused colcop with someone else who I pointed to WOS some time ago, so apologies for taking credit for that)
