| Re: IB Biology HL Exam
The IB utilizes a rule based way to deal with evaluation. This implies understudies work is judged against distinguished levels of accomplishment and not against the work of different understudies. There is thought of the trouble of the exams and the execution of understudies and an advisory group of individuals are included. A few techniques for evaluation are utilized: Assessment criteria when the errand in open finished, Markbands with a scope of level descriptors used to judge understudies answers to some augmented reaction questions, Analytic marks chemes where a specific sort of reaction is required, and Marking notes are utilized to elucidate appraisal criteria. Examiners are checked all through the stamping procedure and ever exertion is made to guarantee consistency in checking. Higher Level In spite of the fact that the length of the considerable number of exams for HL is longer than the SL exams, the structure of all examinations and the examination is the same concerning SL. The main exemption is in Paper 2 where understudies will have a decision of two out of three developed reaction questions. The weighting of paper two is somewhat less that the SL paper 2 to consider evaluation of the additional HL material in the choice paper.

The main exemption is in Paper 2 where understudies will have a decision of two out of three developed reaction questions. The weighting of paper two is marginally less that the SL paper 2 to take into consideration appraisal of the additional HL material in the choice paper.
