Students began the tests with an exam in Polish. On Wednesday, they will have their knowledge of mathematics assessed, and on Thursday their English-language skills.
Pupils must take exams in three compulsory subjects. Most have opted to also take additional subjects, which are required to be admitted to universities, according to officials.
The matura exams are a rite of passage in Poland and determine teenagers’ future to a large degree.
They will be taken this month by 271,000 pupils who have recently graduated from school, and by an additional 96,000 who want to improve their results from previous tests, public broadcaster Polish Radio reported.
Meanwhile, after a period of distance learning, all Polish pupils still at school are set to return to on-site lessons by the end of May following a fall in new COVID infections.
