Yes: the check costs nothing and needs no account, and taking it commits you to nothing.
The check is a short assessment of a few minutes. It gives you a first picture of where you stand: which part of the exam looks weakest, from a small sample. It is an estimate, not a prediction of your result.
The check is not the only free part. With a free account, and without paying, you also get the start of the course: free chapters of the exam’s book — where the exam has lessons, every chapter up to where the first lessons begin — and, where the exam has them, those first lessons and the first podcast episode. And one full mock exam per exam, in the exam’s own format. Your free mock exam counts as soon as you start it, even if you do not finish it. When you buy a pass, you carry on from where the free part ends.
The rest of the book, the lessons, practice, your plan and further mock exams come with a pass for that exam: a week, a month or three months.
The check and the rest of the preparation are in the Licento app for iPhone and Android. You take the check before you make an account; to keep its result, and for every other free part, you make a free one with your e-mail address. Not every exam has a check yet.
