Dude, the times table doesn't take 6 hours a day for 7 years to learn, it can be learned in a month tops. It takes most people who don't do arithmetic regularly a moment to retrieve that knowledge. What you're describing as "poor learning" of the times table is just the regular amount for most people.

Plus, you've gone and showed exactly why it doesn't matter that much: you did INCREDIBLY well compared to the average student and you claim that you can't even do the tasks taught in early education reliably as an adult. Clearly, the skills they were teaching you were not important, if you failed to learn them next to completely and are the picture of success.
