Tutor for Genetics

I am currently in my 3rd year Bsc , i need a tutor to sit through my exam with me in January, id prefer to go through the sample paper together so that you get an idea of the level of expertise needed for the actual exam to see if you are able to do it with me and achieve a grade of 85% and higher. The module is molecular genetics, the exam will consist of 3 questions with 400-500 short written descriptive answers.
