Physics course / Курс по физика (провежда се на английски език)
Standard 11th and 12th grade material based on Oxford and Cambridge textbooks with a focus on SAT and IB test questions. Math includes mostly algebra, trigonometry and vectors, but will touch on dot and cross products, integration and differentiation, and complex numbers.
There will be an emphasis on problem-solving and development of mathematical skills required for (first year) college physics.
Relevant math techniques will be explained in the progress of the course.
Курсът съдържа стандартен материал за 11-ти и 12-ти клас, базиран на учебниците на Оксфорд и Кеймбридж с фокус на решаване на задачи от SAT (Америка) и IB (Англия и др). Математиката включва най-вече алгебра, тригонометрия и вектори, но ще засегне точкови и кръстосани произведения, интегриране и диференциране и комплексни числа.
Ще има акцент върху решаването на проблеми и развитието на математически умения, необходими за физика в колеж.
Съответните математически техники ще бъдат обяснени в хода на курса.

Въпроси и отговори
В: Кой може да се запише на този курс?
О: Курсът е предназначен за ученици от 10, 11 и 12 клас и студенти 1ва или 2ра година, но няма възрастови ограничения. По-малки и по-големи ученици могат да се запишат, ако имат интерес и минималните необходими познания по математика.
В: Защо се преподава на английски, а не на български?
О: Всички материали и онлайн ресурси, които се ползват, са на английски.
Тези, които са запознати с материала, ще имат полза от това да научат англоезичната терминология и да практикуват оригинални тест задачи.
Тези, които планират да учат в чужбина, ще се подготвят за стила на лекциите в международни университети. Всички други ще имат полза да научат терминология, която ще им даде достъп до световното знание.
В: Присъствено ли ще протича курсът или онлайн?
О: Присъствено, като всички, които нямат възможност да пътуват до Благоевград, ще могат да вземат участие онлайн.
В: Какъв е лекционият формат?
О: Форматът е 1/3 лекция и 2/3 решаване на задачи.
В: Ще има ли домашни?
О: Да, ще има обилно количество домашни. В началото на всеки урок ще се дискутират въпроси от предишната домашна.
В: Каква е продължителността на курса?
О: Два пъти седмично по 1.5 ч.
