How different is this course from the Tally Academy online tutorials?

Is this course any different from the Tally Academy online tutorial resources? I know that the syllabus followed by DeZyre is the same as that of Tally Academy.

Also how often has the course (including Quiz/Final Exam) content been updated for this course? Do any updates in Tally Academy course and questions get updated by DeZyre as well?

What's the most popular course of DeZyre to this date? And how many students have completed the 'Business Management using Tally ERP 9' course successfully to date?
