How come they are so enjoyable

Generally, i do not prefer giving exams. So there was no point of giving mock tests at all. However, these TK0-201 practice questions on edusum.com are very interesting and enjoyable. I got hooked on to them and today, when i cleared the CompTIA Certified Technical Trainer (CTT+) certification exam, i realized i gave many mock tests before the actual attempt just for the fun it offered.
