It's the second and final test day of Week 2. You'll utilize plus sets—this time by taking the third set of squats to absolutely failure. Doing as many reps as possible (AMRAP) doesn't mean sacrificing form, however; the point is to see how much you can do safely. Drive your knees outward slightly, above your toes, rather than shooting them forward. This will help keep your back and knees safe from injury.
When you're done, get on with your leg workout, then breathe a sigh of relief; you've finished Week 2 and earned a rest day!
4 sets of 5 reps, go to failure on final set
