Truffles faults !!

On the plan of the organization, the guide is quite well done, although each separate part (French, general knowledge, math exercises, logic, record, etc.), but there are three extremely negative points which render the chaotic progression. First, a simple detail that jumps but still, there are a handful of layout typos and spelling errors. Ultimately, it's not serious. Then, more seriously, under general culture has many contradictions different "one killer" set as chapters, sometimes 20% variance between those who have already been announced and those that remind us later. .. So as we know what to think, we will check the way ... Finally last point, not least, is that the ability of exercises are FOUL truffles !! Especially those on the logical reasoning. Sometimes the statement of the exercise being proposed to do is different from the fixed (to be consulted after they found no logic to the proposed exercise and then understand why ...). So when there is no problem in the statement is the key, which caught: in schedules, for example (and repeatedly), sometimes missing whole sections of what was required to plan, and therefore necessarily the answers to questions that follow are false too. Finally, I noted several exercises including one in particular, who were simply unfeasible because of corrected answers had absolutely no relation with the statement, to believe that the puzzle he had been simplified or question resolved afterwards without the expected answers were changed.
Finally, I do not recommend this guide, there are certainly much better.
