I've passed my KNM but am gearing up for the ​other components for B1 inburgering. I have 1 month to go towards the Luisteren exam. I have been searching online for exam preparation self-study courses and am wondering if anyone has experiences with either of the two sites mentioned. I am feeling my level is a low A2 and am needing a turbo booster in the exam preparations, particularly in understanding the vocabulary etc. Would appreciate if anyone has info on your experience in either the two sites mentioned. Thanks in advance! ​
