For a bookworm, I'm surprised about how much she doesn't know about the world. All she has is "advanced" vocabulary and modern world experience (like hygiene). Other than that, she's lacking a bit.
But I guess there's a difference between reading and doing. I can read about fixing a car, but doing it will be more difficult.
And her stats got nerfed cuz she has a frail body, can barely go anywhere, and is stuck as a commoner (so far).
I feel like this world is supposed to be a learning experience for her about the realities of history, social classes, and education. She died cuz she was so engrossed her own world of books. Hopefully she doesn't repeat the same mistakes in this new one.
Learning to read and write is a step, but hopefully she uses the knowledge from her previous life to help those in need in her new one.
