If your good at english please help me edit the second paragraph of my work...God bless?

I have had work experiences in several different fields. I have experienced being an administration assistant at the Nottingham Trent University. I have worked at Clarks shop as a sales assistant. I have also acquired medical work experiences at Kingsmill Hospital and have been a volunteer helper at Oakfield School for Autistic Children. At Nottingham Trent University, I was able to use my organization skills when scheduling meetings and events for my supervisor. I also developed my communication skills as the job involved me answering student enquiries through the telephone. I believe that the skills I developed from this experience are vital because being more organized means that I will be a better manager of my time and money and this will certainly make my venture to university less stressful and more enjoyable. Working as a sales assistant at Clarks was an opportunity to use my qualitative skills as I worked at the counter. Furthermore, to me, it was a simple model of how demand and supply works and it showed the relevance of price elasticity on demand, as non-designer shoes with a lower price tended to sell more, and also because designer shoes had a high sale number regardless of their high price as consumers were unresponsive to the changes in the prices. The work experience also showed me how marketing and advertising is used to promote the sales of shoes. I also organized a medical work experience at Kingsmill Hospital and I was able to work with people of different age groups, ranging from infants to the elderly as I shadowed doctors in various departments of the hospital. I enjoyed learning about the role of economists in medicine. I observed managerial economists in the medical field work in the decision making about how the hospital works by analyzing various aspects of health care programs and also recommending the steps that should be taken to achieve the aims of the health programs. This experience emphasized the important role of an economist in all fields of life. I have also acquired a three months work experience at Oakfield School, which is a school for Autistic Children. At Oakfield, my role was to help and teach the children subjects such as geography and math. Teaching the children highlighted the importance of speaking clearly when explaining things and giving instructions.
