Ms. Chesher is a very easy teacher to deal with. As long as you do your work to the best of your ability, you can expect a relatively high mark. However, she appears to be bored with her job and doesn't seem to try too hard, so if you want a teacher who tries at their job, this is not the teacher for you. Overall, she is not a strict teacher, which is probably a good thing for every student as no one wants a strict teacher. Most likely you will enjoy your experience with her, just try to behave yourself as if it is your goal to piss her off, it will not work.
