Mobile Infrastructure Training

Are classes TMOB20 and TMOB40 still being taught? I saw no upcoming sessions, but I saw OME25S available (because it's an online course).

There isn't much description for OME25. From some sentences it seems to be both TMOB20 and TMOB40, but with recorded sessions. Is this true?

And does anyone know about TMOB20 and B40 courses? Any experience taking them? Comments?

Thx.
