Did I get smarter based on this information?

When I was in my late teens I would always misplace my things, it happened at least once every 4 months and maybe as often as three times a month. I also got D’s in university. Now I have not lost an item in over 12 years and I get angry when I get an A and not an A+. The one thing about me that was better younger was I could memorize 300 pages a day when I was 18 and I could also think faster than 99.998% of all people which was proven through IQ tests. But when it came to science classes in school, I had terrible logic and was lucky to get above a C. I almost failed my first year in the gifted program as a teen. So grades improved and I stopped losing things but could no longer memorize 300 pages a day.
