Dear Girish

Inorder to do the training in the Larsen's and Turbo organisation you need to apply for the training from their official Website. Mostly they will conduct the training in two sessions which will be held in the summer and winter. So inorder to do the training in these two sessions you need to apply from 2 - 3 months before that such that you can be able to occupy the seats. And for the duration point of view you can do it accordingly of your own convenience .

All the best
