Very Challenging Mock tests on Edusum

I feel sorry that i did not know about edusum during my first attempt or i would have passed it. I got 87% in the second attempt for GCSA and am happy. The mock tests on the site has questions in random order with shuffled multiple choice answers. This made the exam experience very challenging. I was able to view the result of every exam and even performance history of the past attempts. The facilities available on the site are great advancement over the age-old pdf formats. The site is very reliable too to practice for GCSA.
