Academy: reader, quiz, lab and exam

A faster Academy with a redesigned way to learn

Lessons load as you open them, with worked examples, tooltips, hints on selected questions, one-at-a-time quizzes and a timed exam with a results page.

Free taster, the rest Pro

Academy: feedback and help

Rate, report, ask and request an expert review

Tell us what is unclear or broken and ask the team a question from inside a lesson. Comments and expert-review requests are Pro; there is no help during an exam.

Questions and reports follow the Free taster

Every figure names its source and the date it describes. Backtests replay history after estimated costs; they do not predict the future, and a weak result is shown as plainly as a strong one.

Learn it properly.

The TellHawk Academy has 170 modules and 724 lessons across 4 academies, with labs, exams and a certificate for each of three levels, plus feedback, problem reports and questions to the team inside the lessons. Education only, not advice.

Explore the Academy
A lesson in the Academy reader with a contents list on the left, and in the lesson a worked example with a Show the working section to expand, a green tip titled Round down, never up, and a red common mistake callout about sizing from the amount you want to make.
The reading view: a contents list that follows your place, callouts (key idea, worked example, tip, common mistake) and a section you expand to see the working. Notes and warnings are callout kinds too. Demo data: made-up content and a sample learner, not a real account or result.
Exam results showing 60% against a pass mark of 70%, a by-topic breakdown with Risk and position size marked Below pass mark, a What to study next list that links to three lessons, and the start of a question-by-question review.
Results: your score against the pass mark, a breakdown by topic, links to the lessons to revisit and a review of every question. This demo attempt did not pass, to show the study-next list. Demo data: made-up content and a sample learner, not a real account or result.
