The Quartic slides, videos and question banks cover every learning outcome statement (LOS) in the curriculum. Our authors are all CFA charterholders: we use our judgement and experience to determine the required depth for each concept, but it is our intention to provide sufficient explanation to be able to answer virtually every exam question. The underlying CFA curriculum is significantly longer (in print form, more than 4,000 pages at Level I!) and it is impractical for Quartic to achieve 100% coverage.
