What is the difference between e-Learning of ECC 6.0 and OLT (Online Trainings)?

Trainings in ECC 6.0 may be delivered through Instructor-led (ILT) classroom based trainings or by way of Online Trainings (OLT). Only a small portion of the total training in ECC 6.0 is delivered as e-Learning for those candidates to opt for ILT trainings. Balance training is necessarily covered in the classroom by an experienced and certified faculty when the candidate chooses ILT. In case of OLT, the entire training is delivered as e-Learning at the Training Centre.
