Chapter 12 Axisymmetric (not difficult)

Chapter 13 Real Numbers (Not Difficult)

Chapter 14 Linear Functions (Simple after Understanding)

Chapter 15 Factorization of Algebraic Expressions (Do more problems, remember the algorithm and summarize appropriately)

In short, the knowledge of mathematics in the first semester of Senior Two lays the foundation for the mathematics study in the next three semesters (such as quadrilateral, inverse proportional function, quadratic function, quadratic equation of one variable, similar triangles, quadratic root ...).

Be sure to study hard, especially "congruent triangles", which is the basis of geometry, and there are many kinds of questions.

I wish you success in your study.
