AP Calculus AB is designed to be the equivalent of a first semester college calculus course devoted to topics in differential and integral calculus. The course features a multi-representational approach to calculus, with concepts, results, and problems expressed graphically, numerically, analytically, and verbally. Exploring connections among these representations builds understanding of how calculus applies limits to develop important ideas, definitions, formulas, and theorems. A sustained emphasis on clear communication of methods, reasoning, justifications, and conclusions is essential. In May, students should plan to take the AP Calculus AB exam for possible college credit (each college determines credits earned). A fee is charged to take the AP exam.

AP Language & Composition
1 Unit | English Language Arts | Grades: 11, 12
AP English Language and Composition focuses on the central question, “Why was a text important when it was written?” As we analyze a text from this perspective, considering how the author would have considered their purpose, audience, and situation, we also develop the transfer skills to make those determinations about our own writing. As such, we develop the skills to consider a rhetorical situation as both reader and writer, which we can use in any context. Given the course’s focus on the rhetorical situation, we will read and write in a variety of genres (both academic and professional) as we prepare for both the AP English Language and Composition Exam and collegiate-level, academic writing. Since most students have the potential to earn credit for a college composition course with the successful completion of this exam, students should expect that most writing assignments will go through multiple drafts, with teacher, peer, and self-evaluation all part of the writing and feedback process.
AP Literature & Composition
1 Unit | English Language Arts | Grades: 10, 11, 12
The AP English Literature and Composition course is designed and taught through a mixture of themes and genres to develop students’ skills of analyzing literature based on genre structures and characteristics and to develop students’ ability to connect related literature under an overarching theme while also engaging with the required Big Ideas. This course closely follows the requirements described in the Course and Exam Description (CED). Students will read and study a variety of novels, plays, poems, and short fiction from the 16th century to the present from Literature and Composition: Essential Voices, Essential Skills. Emphasis is placed on developing independent reading, writing, thinking, and analytical skills through experiencing and writing multi-paragraph, literature-based compositions with an emphasis on expository development and developing student voice. Students will practice writing through numerous timed essays, which will be revised, as well as longer, MLA-formatted, researched essays. Students will also practice oral communication and writing for various audiences. This course will help prepare the student for the rigors of a college education.

AP Statistics
1 Unit | Mathematics | Grades: 10, 11, 12
Students analyze data with calculators and computers, conduct classroom experiments, and perform simulations involving probabilistic concepts. Moreover, these students would not necessarily be enchanted by a traditional mathematics course. The AP Statistics course not only accommodates students with a wide variety of interests, it also serves those with a relatively wide range of math proficiency. Because the science, art, and practice of statistics differ significantly from other fields of mathematics, it is not surprising that this discipline is also taught differently. The purpose of AP Statistics is to introduce students to the major concepts and tools for collecting, analyzing, and drawing conclusions from data. Four broad conceptual themes are exploring data, planning a study, anticipating patterns, and statistical inference. Students are expected to take the AP exam and those who successfully complete the course and examination may receive credit, advanced placement, or both for a one-semester introductory college statistics course.

Not only does Cybersecurity introduce the breadth of cybersecurity concepts and skills to students, but it also prepares them to verify their technical know-how through the CompTIA Security+ certification
English I (Honors)
1 Unit | English Language Arts | Grades: 9
The purpose of Horizons Advanced English I is to train students to notice the critical features of a text so they may “unlock” the nuances of the author’s craft in order to better understand the message, intent, and impact of a text. These nuances will often include analysis of how the author’s use of word choice (both figurative language and literal meanings) can affect a reader. As students understand how authors use their craft both stylistically and for precision, they can begin to focus on their own writer’s craft by focusing first on academic sentence structure and then building upon these skills to develop well-organized paragraphs and, with academic growth, responses of greater length or complexity. Students and mentors may notice that the skills of analysis and response are emphasized during ELA coursework but easily transferable to many disciplines and areas of study. Advanced English encourages reading comprehension, analytical response, academic research, study of rhetorical techniques, and discussions throughout the curriculum.
English II (Honors)
1 Unit | English Language Arts | Grades: 10
Horizons Advanced English II builds on the foundation of the Horizons Advanced English I course by utilizing the recurrent OSDE ELA standards of instruction to achieve the continuing goal of developing the critical thinking skills that students will need for success in high school, college, and life. While Advanced English I introduces the fundamental routines of analytical reading, critical thinking, and evidence-based responses, Advanced English II directs students to apply those same scholarly discussions to new and various literary and non-fiction texts. These continuing learners will improve their awareness and appreciation of an author’s ability to masterfully manipulate language to serve the unique purpose of each writing. By continuing their studies of an author’s syntactical style and precision, students in Advanced English II can continue to practice crafting their own compositions into more refined essays and multi-modal responses in preparation for the challenges and nuances of advanced communication for both the collegiate campus and the workplace. Advanced English II (10th Grade) encourages reading comprehension, analytical response, academic research, study and utilization of rhetorical techniques, and discussions throughout the curriculum.
