Unfortunately, the ESAT specimen paper is basically the same as the NSAA specimen paper, and the ESAT practice paper contains questions drawn from NSAA past papers.
This is really bad, because lots of students will have reserved the online ESAT specimen and practice papers for final prep, but when they come to them they'll find they've seen all the questions before. D'oh! Not to mention that the papers have been offline for part of the weekend for site maintenance. Can you believe it?
