I have a close friend of mine who underwent the audition circuit for three years running (I accompanied her for moral support during her third attempt) and she finally managed to gain a place at RADA on the BA (Hons) Acting last year. I use to live with her until recently, so I'm well aware of her weekly routine, in addition to knowing many of her friends on the course. Furthermore, I also knew a few people that went to the Drama Centre London (part of Central Saint Martins, where I studied).
It's safe to say that the course is extremely demanding, like most NCDT/CDS accredited drama schools, where she is required to attend, on average, five days a week, 9 until 7, possibly longer, and occasionally during the weekend as well (for rehearsals and final productions). The day is mostly comprised of movement classes (that can be improv or on a specific dance style), individual or duologue tutoring, vocal/accent training (similar to elocution), class rehearsals, and amongst many other specified classes. I don't know the exact ins and outs, naturally, but that's a rough outline.
I'm referring largely to Acting courses (not Musical Theatre), so it's dependent on whether the course in question has an MT element. Some courses do not require the students to sing, although I believe many do have optional singing classes. My friend can and does sing, although it isn't the primary focus of the RADA course. I believe at Central, they have individual strands/pathways, one of which is Musical Theatre.
Camera work isn't introduced until the second year for RADA. This will obviously differ on the drama school and course. RADA is predominately concerned with theatre based performances, but they do release regular short films too, throughout the year. However, much of the camera work is intended to produce showreels for each student. The showreel will usually consist of a chosen play that the student performs, whilst filmed.
I'm probably missing stuff out, but hopefully I've given you a rough gist of what happens during drama school. I cannot emphasize how intense these courses are, though. That said, the amount of work clearly shows. I have attended many RADA productions and I'm consistently taken back by the standard.
