I do not recommend TEST-HELP.com for preparation. The thing is, there are a lot of errors in these tests, which are present not only in the solutions but even in the problem statements! As a result, it is simply impossible to solve their questions. Moreover, the tests themselves are nothing like the real ones – neither in structure, nor in question types, nor in duration. For example, their tests contain only 10 questions, while the real test has 30-40 and even 50 questions. Therefore, preparing with their tests is completely pointless.
