O wise ones....

Don't get worried about anything right now, it's seriously not worth worrying about it your stage.

Tbh I'm not worried about [s2]. It's mainly [s1]. Does spamming [s1] improve 'critical reading' and stuff?...or is it mainly 'natural ability'...

It's a bit of both, yes it's trainable, but only to a certain extent, you'll see that once you reach a certain stage, you start to asymptote towards a particular level...that's what I found anyway, so it's about maximising your potential, and also, speed training is also important, just finishing S1 will give you a HUGE advantage over others
