A student must do his own studying, his own exercises, and ultimately, his own learning. MOST people who study Chemistry need some instructive guidance, and a suitably equiped and supervised laboratory, and must make formal use of a textbook for the course/courses. ALL people who study Chemistry must do laboratory activities. One must assemble and adjust equipment and learn to handle materials. Much of everything relies on the students actions and on the students thoughts.If they want to do lab work the should have a lab course, but in terms of knowing chemistry I was a told by a soft matter theorist that was a one time in a chemistry department that they basically learned all the chemistry they needed by themselves. I would just take the intro sequence and you should be fine after that.
