Difference between self-paced and online instructor-led course

I can see that there are two offerings, self-paced course and online instructor-led course. May I know the difference between both?

Greetings from CloudxLab.

In the self paced course on Big Data with Hadoop and Spark , you will get life time access to all the latest study content – slides, videos, examples, quizzes, assessments, project etc. In addition, you will get 90 days of free access to lab for hands-on practice. All of your doubts and queries will be resolved over emails.

In the Instructor-led course, there will be 40+ hours of live online instructor-led sessions for training and query resolution. These live online sessions will be conducted every Saturday and Sunday starting from May 27. In addition to these live instructor sessions, you will get lifetime access to all the study content. Furthermore, you will get 90 days of access to lab for hands-on practice. Also note that if you enrol to our instructor led course now, then the access to lab and study material will immediately become available and you can get well prepared for the instructor led sessions that start from May 27.

Let us know if more clarifications​ are needed.
