Unlimited practice attempts are best

If at first i do not succeed, i can give it again. And again if i not succeed, i can give it once again. And the series goes on. Because LPI Linux Administrator mock tests give the benefit of unlimited practice attempts. This is not possible in other type of resource material. My teacher always said that the more you practice, the more you learn. And i learnt to make a strategy to clear the upcoming exam that i require for my career.
