3ds Max is still one of the tools studios and visualisation teams ask juniors about, especially for hard-surface models, interiors and general 3D production. A useful course is not a tour of every button. It is a sequence of models that get harder, with critique on proportion, topology and how the scene is named.
At Pepper Animation in Rohini the 3ds Max classes sit beside the wider 3D and multimedia programmes. Students work from references, learn modifiers without turning every object into a mess, and leave with stills they can explain. If you are choosing a class in Delhi, ask who reviews the work, how large the batch is, and whether you finish a piece you can put in a portfolio.
The toolset is broad: modelling, materials, lights, cameras and a first pass at animation. You do not need all of it on day one. Start with clean models and honest lighting. The rest of a 3D career is built on those two habits.
