How many correct answers do you need to pass?
The passing threshold is set by UHR and published in the test description. We will state it here once it is confirmed.
This question depends on information the authorities have not yet published. We'll update the page as soon as there's news.
We don't want to publish a threshold we can't back up, since you might plan your studying around it. As soon as the figure is published by UHR, we will add it.
Practical advice in the meantime: don't aim to just barely reach the threshold. Aim to understand the topics. Then you'll have a margin regardless of where the threshold is.
