In learning q most of us have to drop the habit of edging into a solution with loops and think instead of vector operations. The transition is typically both awkward and exhilarating. It is harder if you are a solo student without vector-savvy colleagues to learn from.
Is that you? Consider taking part in my research project. I want to discover how best to help students like you through the transition. The end result will be online self-study resources, but the project starts with online workshops.
The training is not offered by KX but by me personally. Details at
