Karen assumes too much prior knowledge of mathematics. She also attempts to cram too much information into her lectures, and doesn't go into much detail in the explanation of the slides and methods in finance study.
The mid semester contained questions which were not fully covered in the lectures.
The use of the calculators is an issue, as financial calculators are quite expensive, and she doesn't offer many equations for the formulas she wants you to solve. Google helps a lot here.
However she is a good tutor.
Her lectures attempt to cover too much content and she makes mistakes while doing computation questions (which are extremely confusing to begin with). She also assumes too much prior knowledge of maths (which commerce students might know but business students find confusing) and is reluctant to help if you don't understand. Finally her exams are really tricky and have added parts which were not covered in detail in the lectures- people even walked out crying from the final I had. That said she does give up her time to help students (through online consult) however shes way too distant from the students- not the best lecturer for such a difficult subject.
Karen provided a wealth of knowledge accompanied by a way of succinctly explaining complex topics. Unfortunately, the course she teaches is so packed full of information, she must move at quite a fast pace.
She seems to assume a bit of prior knowledge, even though there are no such pre-requisites for the course. This does not necessarily reflect negatively upon her as a lecturer.
She seems very organised and motivated to do well.
