I haven't posted a blog for awhile now, but I'm continuing to move through the Playground. I had done numbers 1 to 10, and stopped at that point. Now I'm doing the required 16 to 20, and taking the short tests with each. Did well on the tests. Number 18 was a lot to read. Number 19 was very interesting, and I found the information I was looking for with ease. On to number 20 next week.
