I 100% agree with moving on and studying for the next section.
At the same time, I also agree with a break after taking an exam. I'd usually at least take a break through the next weekend, usually with the goal of a week-long break (tested on Wednesdays), but usually ended up studying before the whole week was over.
If you're feeling like you need a break, then go ahead with a break, just set a specific end date for the break, and then move on to REG soon as you hit that end date. If you want a 10-day break, then that'd happen to coincide with score release. That's just 1 weekend and a work week; scores come out on Friday, so you'd be ready to hit the books Saturday for whichever test you end up needing to study. However, if you don't feel the need to take a 10-day break, and maybe just want to take a break – say – through Saturday, and start studying this Sunday so that you've got Sunday and Monday both to study before you start back to work, then go for it. Moving on is generally a good idea. Take whatever break you need and then move on, don't wait on scores, unless the break you want and the date of score release happen to match up perfectly.
