I've studied 1st part of Minna no Nihongo (chap 1-13) around 4 years ago and since then stopped learning any Japanese. Recently I would like to resume my learning on Japanese at Ikoma. Knowing that there's a placement test, but also knowing that Ikoma's beginner course consists of both parts of Minna no Nihongo 1st book, I'm wondering if there's a possibility that a placement test can put me on a start from the 2nd part of the book rather than starting from fresh. Anyone has such experience? Also, if I were to take the placement test knowing that I can only answer those related to the 1st part of 1st book, anyone know how the placement test will look like (or any tips?). Thanks.
