Ah, those pesky AMCs, thanks.
This theoretical knowledge instruction provided by the ATO should include a certain element of formal classroom work but may include also such facilities as interactive video, slide or tape presentation, computer-based training and other media distance learning courses.
So, a conservative cumulative 5 hours of pre- & post-flight briefings + 95 hours (ahem) of home study will satisfy EASA.
For one ghastly moment I thought every student would have to sit through 100 hours of classroom before taking the exams.
