I find myself scratching my head and wondering, "Why?"
1) You are obviously an established shopper getting shops easily enough since you are still shopping after 9 years.
2) You are obviously writing 'better than the average Bear' if you are getting mostly 10s on your narratives. I would suspect that 'Professional Industry Writing' is likely to be very basic, such as no opinions, match of noun and verb for number, writing in the past tense, etc., so I fail to fathom why you anticipate it would be useful.
If your goal is to take classes, there are free on line writing classes, or computer classes, or car mechanics classes or any of a number of on line free classes to meet your interests.
