Let me try to answer that.
Upgrading is very important before training starts, so that the student gets going and is set up for success.
Let me give you an example. For the surveying course, we really have to ask the instructors to check the mathematical concepts required, the ones the student has to know in order to be able to successfully complete the training. Before training starts, we do three weeks of life skills. That is also when we work on the students' mathematics. Those are services that we provide. And if the students do not have the prerequisites, we also help them in terms of coaching them through instructional development tests.
