I did that quilt a couple of years ago for a pp'ing class. It really isn't that bad - the arcs are pretty skinny but mine went together fairly well. Since it's paper pieced it's quite accurate. The HST's are generally the issue so I would recommend cutting them larger and trimming down just to be on the safe side - unless, of course, you have mastered those! I have not. Now, if I could only figure out how I want to quilt mine??? I hand quilt so it's been a challenge to come up with a design that won't detract from the quilt or make me crazy with managing a bazillion seams. Thus, it's still a flimsy.
