Nephrology questions for medical students

I am looking for qualified doctors (or graduates in appropriate sciences) to write practice questions for medical student exams. For this project, I am looking for 160 questions about nephrology that are to cover histology, anatomy and physiology in a systematic manner. Questions must be in a 'best of five' format, where after the initial question of 20-100 words, 5 options are presented for the candidate to choose from. Only one of these options is correct, but all should be plausible to a candidate with a low level of knowledge. An explanation of 80-200 words must then follow and discuss correct and incorrect answers. 50 questions must be accompanied by an image which can either be sourced from the internet (with an appropriate reference) or be produced originally. Please state clearly in your bid which option you can provide. Further details are available in the attached file and on request. All questions must be at a suitable level for UK undergraduate medical examinations. If you are interested in bidding for this project, please state the qualification that you feel makes you suitable for this work. Also, please provide a sample question. Payment will be made on completion of the project, with a single milestone payment available on delivery of the first 80 questions. Please not that all submissions will be check with plagiarism software that scans both digital and print media.
