International Baccalaureate IB Biology Past Papers Higher Level (HL)
International baccalaureate (IB) is an International Non-profit Organization, which offers Four high-quality International education Programmes (Primary Years, Middle Years, Diploma, & Career-related) to students from age of 3 to 19 in more than 146 countries. It’s formally known as International baccalaureate Organization (IBO).
IB Diploma Programme’s aim is to develop high school students who have excellent breadth & depth of knowledge – and who flourish physically, Intellectually, Emotionally & Ethically. IB Diploma has 6 groups to choose the subjects; Group 1: Studies in Language & Literature Group 2: Language Acquisition Group 3: Individuals & Societies Group 4: Sciences Group 5: Mathematics Group 6: Arts
International baccalaureate (IB) Biology Subject comes in Science group of IB Diploma Programme after 10th or secondary education. Here, High school or IB Students will get all the guidance, Notes and the Past papers of IB Biology HL, that will help you to understand about the level of this test and to achieve High score in Exam.
