Repetition alone is unlikely to lead to improvement in any skill.

What is needed is deliberate, directed, purposeful practice.

An honest assessment of Planturo thus far is that it is mostly repetition, not purposeful practice.

If that’s the case, then I need to direct my effort:

What are the elements in the process of writing? How to practise and get better? Does it help to imitate – take the sentence structure of good essay and rewrite in own content? Etc

Although Planturo right now is not leading to better writing skills, I think it is helping in other aspects – namely crystallising thoughts, and retelling or reflecting on new informarion or skills learnt.
