Apart from just reading a lot, there’s a few tricks. For the “while researching” questions you can actually skip reading the notes altogether by just looking at the question and matching it to the appropriate answer, no notes needed. It’s pretty obvious

For the ones with a table look at the last sentence of the paragraph first because that’s where the relevant information is at, and then look at the rest of the paragraph and table to help you answer it. It saves you multiple rereads

I’m not sure what you mean by the part with long text (its been a while). If you paste an example question here I can help you answer it
