semestra

A semestra is a unit of time used in some academic institutions, typically representing a half-year academic term. It is derived from the Latin word "semestris," meaning "six-monthly." The academic year is usually divided into two semestras, often referred to as the Fall semester and the Spring semester. Some universities may also incorporate a summer term, which can be considered a separate session or a shorter, optional semestra.

The duration of a semestra can vary but generally spans approximately 15 to 17 weeks of instruction. This period includes lectures, seminars, laboratory work, and other academic activities. At the end of each semestra, students typically complete their coursework through examinations, projects, or other forms of assessment. The semestral system is a common structure for higher education globally, facilitating the organization of curricula and the progression of students through their degree programs. The break between semestras, often called the winter break or summer break, provides students and faculty with a period for rest and preparation for the upcoming academic term.
