Avoid thinking about specific topics and consider "competency".
At uni it is going to be expected automatically that you are competent, confident and correct in fields such as algebra, differentiation/integration, graphing, statistics, geometry and trigonometry.
While a lower level maths course might include a topic on say trigonometry, and you might remember a couple of equations, you are certainly not going to be as competent, confident and correct as a 3U student.
A 3 week bridging course is probably not going to make up for not doing 3U maths for 2 years in years 11 & 12.
It is always my blanket recommendation to students that 3U maths is assumed knowledge, and that 2U students must do a bridging course and work very, very hard on maths. I would actively recommend against a 2U General maths student from engineering.
Universities set assumed knowledge standards for a reason, however they wont set them as an absolute set in stone pre-requisite.
