Tips/Tricks to doing RC on computer?

Hi,

Does anyone have any tips or tricks that would make doing RC on the computer easier? As I'm doing practice problems in the OG, RC is not a problem since I am able to mark up the passage and circle/underline anything I deem important. This is a huge help! However, I obviously can't do this on the CAT.

Is this just about practice, practice, practice and becoming familiar with doing RC without markups? Should I jot down notes in the provided notepad?

Any personal tips or tricks would be appreciated!

Regards,
Rich
