This is what I think is the best stat spread for up until you arrive in your bedroom at the Doctor's house, as far as doing conversation checks goes.



Opening Tombstone:
The stat you should skip is Literature & Writing, while choosing every other stat once. I'll add an answer key below.

1st level up: + 2 History & Politics, + 2 Literature & Writing (technically optional,) and + 1 Science & Logic.

2nd level up: + 5 Arts & Music.

And I used my free book point on Literature & Writing, but you can do whatever you like with it.

This way, you'll only have to skip two potential conversation checks, and I believe get as much xp as possible.

I didn't feel like this was super necessary, but I figured I'd type it up really quick anyway.

Here are all the things that I'm aware of that give exp, but if anyone knows something I missed, let me know and i'll update it :D

This is everything I've found that gives xp for interacting with it, most things you can click on don't. There are other things that give xp as well, but they are things you can't avoid, like going into a room or putting on the new dress.
