For many students, Algebra 2 is the last math-barrier you have to get over in order to graduate.
This class will build on a lot of what you've seen in Algebra 1. You will review what you have learned before. If you know of a topic you struggled with back then, don't dismiss it this time around. You are older and wiser now. Tackle the topics with the belief that you can learn it now, despite how you have struggled in the past.
Then there will be a handful of new operations to learn how to manipulate and graph. You can do it!
Some students will take Algebra 2 with the midset that they are only part-way through their study of mathematical subjects. If this is you, you should always be working for perfection. Prepare yourself as much as you can for the next level (preCalculus/Trigonometry)
