This course teaches every aspect of Task 1 (Academic), which helps you to get Band 7 or more in the first attempt.

This is well-elaborated step-by-step video course, which teaches you every aspect of task 1 in simple words.

With my experience, I believe that achieveing high-band score in task 1 is far easy than task 2 because it needs limited amount of words and sentence structures which helps you to achieve Band 7.
