Course Description:
This course is designed for the most successful mathematics students who either have a genuine interest in mathematics and enjoy meeting its challenges and problems, or need such mathematics for further studies or related subjects such as physics, engineering, and technology at university level.
This is the second year of the two year IB MATH High Level course, and will cover following topics:
Core
• Algebra
• Functions and equations
• Circular functions andtrigonometry
• Matrices
• Vectors
• Statistics and probability
• Calculus
Options
• Statistics and probability
• Sets, relations and groups
• Series and differentialequations
• Discrete mathematics
Portfolio
Two individual pieces of work based on mathematicalinvestigation and mathematicalmodeling
All seven core subjects are required and one of the four options must be chosen.
Assessment:
In High Level IB Mathstudents will be assessed using tests (multiple choice, short- and extended response questions), quizzes and homework. Students can expect tests to be of same level as the IB examination.
Grading:
Homework Quizzes: 20 %
Major Quizzes: 20 %
Exams: 60 %
Homework
The homework grade: you’ll have quiz on the homework. That will be student’s homework grade.
Major Quizzes and Exams:
Major assessments will most commonly consist of IB-style assessments. Major assessments will receive both a North Hills grade on a 100 point scale and an IB grade on a 7 point scale. The 100-point scale grade is calculated as part of the quarterly course average and will be posted on Powerschool.. The IB 7 point scale grade is not calculated into the course average, but is included as a predictor as to how students are likely to perform on the IB Math exam in May.
In accordance with NHP’s assessment policy, if a student fails his/her exam they may schedule a re-test to earn up to a 70%. If a student retakes an exam, their second score will stand (up to a 70% max), even if the score is lower than the first exam score.
Grading:
Homework Quizzes: 20 %

Exams: 60 %
IB Assessment
Students’ success in the mathematics higher level course is measured by combining their grades on
external and internal assessment. The internal assessment is of each student’s portfolio, which consists of two pieces of work demonstrating ability in mathematical investigation, to highlight that investigation is fundamental to the study of mathematics; and mathematical modeling, to translate a real-world problem into mathematics.
IB External Assessment: (conducted externally by IBO – 80%)
▪ Paper 1 (HL ) 30% of the IB External Assessment grade.
Short- and extended response questions on the core (no calculator allowed)
Time: 120 minutes
▪ Paper 2 (HL) 30% of the IB External Assessment grade.
Short- and extended response questions (with graphic display calculator required)
Time: 120 minutes
▪ Paper 3 (HL) 20% of the IB External Assessment grade.
Option
IB Internal Assessment: 20%of the IB grade.
Tutorials:
Students are strongly encouraged to seek tutorial help the moment they realize they are not mastering key knowledge and skills.
Unit Syllabi:
Unit syllabi covering class activities, exams, projects, readings and other homework for each unit are available online on the IB MATH HL web page. In addition, the syllabus for the first unit is attached to these course guidelines.
Course Web Page:
The course web page is located at Simply click on the “Faculty” tab, then “Radja, Bojana”. In addition to syllabi, class notes, markschemes (rubrics), guidance on the IB MATH Portfolio, and a variety of other resources are available on the course web page.
