STRUCTURED QUESTIONS FROM PAST PAPERS

Youtube Links for Complete Video Solutions for Structured questions taken from IBDP Past papers are shown below. The problem notation given below denotes the Concept / Chapter number ( taken from the same chapter names as shown above in MCQs classification ), followed by the year of exam and Actual question number in paper -2 / paper -3. Some questions may belong to more than one chapter and the chapter numbers are also indicated. A brief excerpt of the beginning of the question is also shown below each problem for your reference. 

NOTE: Though most of the questions taken here are from HL papers, there is a significant overlap between SL and HL and in fact, HL questions are covered in depth and hence HL questions are used as a reference.

Happy Learning!
