Much more than effective than PDF files

I say this because i have experienced practicing with both, PDF files and Paid ISTQB CT-GaMe online practice tests. They are both very different in presentation and practice. Obviously, i loved the simulated tests for CT-GaMe exam, they are a refreshing breath of air. It helped me change my mood and practice with energy. I scored good in CT-GaMe and the credit definitely goes to this site.
