I bought a package with an online course and 20 tests good for 3 months. I studied by myself and called 123 a few times with questions that were immediately cleared up by the staff. Though the translation to English is not always perfect it made NO difference in the end. My test was in English and so similar to the 123 tests that I almost forgot I was at the CBR. I made only one mistake! I highly recommend 123-theorie.
