What solution do you use for grammar writing?

@shashcoffe I grew up watching A LOT of American cartoons (I'm Indian and grew up in India). Much of my language learning came from imitating what I saw on TV. Because I never had any formal training in the language (admittedly, I never paid attention in grammar class at school), my grammar was okay, but I never really knew, for instance, why 'fewer' and 'lesser' were different words, or that 'which' and 'that' have very specific uses. There are several more examples I can share, but I'll stop at two for the sake of brevity. I coasted through 30 years of my life, working as an editor and a journalist and then switched to content marketing before I decided I needed an MBA. It was only during prep did I realize that a lot of my fundamentals were flawed. Maybe 50% of my answers would be correct, and not being able to explain why my choice was wrong and why the other one was right made me want to take grammar seriously. By my own admission, I'm still average, Grammarly routinely exposes my inability to use a comma properly, but the hours I put into prep have made a difference when I proofread the copy written by my teammates, and I have a valid explanation of why it should be written differently. I apologise for the long read. I hope this helps :)
