The IB Physics B examination consists of two three-hour papers. Paper 1 contains questions on Electromagnetism and Classical Dynamics, Paper 2 contains questions on Electromagnetism, Classical Dynamics and Thermodynamics. The Part IB syllabus was extensively changed at the start of the 2003-2004 academic year, and again for the 2007-8 academic year: examination papers from earlier years will not correspond to the current IB course.
The practicals are continuously assessed and overall count 25% towards the IB Physics B examination, with about half of the 25% coming from a formal report on one of the experiments; full details are in the class manual and additional help is given in the booklet Keeping Laboratory Notes and Writing Formal Reports.
An official statement will appear in The Reporter. For the most recent published version, see the Form and Conduct Notice (scroll down for the Physics entry).
