The best place to practice

I passed my base certification exam at first attempt with 96 % some time back and this time I took SAS BI Content Developer with the help from this web.
when I bought the practice exam provided here by, I had already completed studying prep guide by SAS for the A00-270. so I got 72% in my first test. although, eventually I started getting higher Percentages as I keep practising. I even scored above 95 % for my last few attempts. Most of the questions were similar in the exam with some minor changes. so if your concepts are cleared and you practised with practice test you will definitely pass the exam easily.
Good luck
