Advanced Level Chemistry at Doc Brown's Chemistry Clinic: Science-chemistry for revising course content for learning teaching tutoring e.g. revision notes on NMR spectroscopy problem word equations balanced symbol equations structure formula/formulae annotated/labelled diagrams apparatus information methods of preparation described properties defined explained facts data concepts principles theory explanation descriptive/descriptions definitions revision notes for NMR spectroscopy problem, tests and multiple choice quizzes for NMR spectroscopy problem, worksheets for NMR spectroscopy problem, practice questions for NMR spectroscopy problem covering: AQA Advanced Level Subsidiary AS Chemistry Advanced A2 Chemistry, CCEA Advanced Level Subsidiary AS Chemistry Advanced Level A2 Chemistry, Edexcel Advanced Level Subsidiary AS Chemistry Advanced Level A2 Chemistry, OCR Advanced Subsidiary AS Chemistry Advanced Level A2 Chemistry, WJEC Advanced Level Subsidiary AS Chemistry Advanced Level A2 Chemistry, IB Advanced Level Chemistry, CIE Cambridge International Advanced Level Chemistry, SQA Scottish and Irish Higher Certificate Chemistry, I know quite a few teachers find the site helpful revision for 'professional development' of their teaching as well as their students revision of NMR spectroscopy problem. However I DO NOT DEAL IN PAST EXAM PAPERS - you get them from the examination board or your school/college teacher, not from Doc Brown's Chemistry Clinic!
same price to you, but helps support the site!
