Detailed result history is beneficial

Like generally, how are results given. There is just a score given and we have to guess where did we fail and what could have been better in our 101-500 practice exam performance. But with these practice questions, the result is given in detail and I knew exactly where I went wrong and how should i prevent the mistake in the future. So there is no guess method or trial and error method that is working. This helps in completing the practice for the LPI Linux Administrator - 101 certification exam in just two months.
