Course videos on CCNP Encor

After completing CCNA course, I have started with CCNP ENCOR. But on my portal there are two tabs for CCNP ENCOR (350-401). First one is CCNP ENCOR (350-401) by Mr. Sumit and the other one down to this is CCNP ENCOR (350-401) Alternate videos by Atul Sir. Now I dont know whether both of them have same contents or do I need to cover both the tabs to complete CCNP ENCOR?
Please guide.

Think in this way you have options to learn from both Trainers;
its good if you have both content !!
