How reliable is Accowtancy Classroom

Im currently looking around for an online learning provider for SBR as most learning providers at my region have started their classes in January (my learning provider just released their timetable and SBR is not provided).

So how reliable is Accowtancy’s classroom is it sufficient and what’s the difference between the ultra option? Does anyone in this community ever used it? Appreciate the feedback 🙏🏻🙏🏻
