I like to build myself a problem set of 10ish 1-star LR questions, in question types that I feel confident about. If you want to avoid being tripped up you could also try picking Qs you've done before (7Sage keeps track for you so you can see you've taken it x amount of times). I've also seen other people do a 1-star LG but I find it helps me more to cycle through a few totally different questions vs focusing on full games.
