I Am a Bad Speller

The only reason my spelling appears to be on point, besides the fact I know the spelling of some basic words and words I've used a lot, is because I use Grammarly. So to show that I truly am a bad speller, I'm typing this without correcting my spelling. Like seriously how am I a bad speller but am somehow a good reader? If it weren't for spell check almost all my essays would have bad grades due to my horrible spelling. Anyone else out there a bad speller? Damm it is this really going to end with my having great spelling, because that's just not how I am.
