I have recently left the RAF where I served 10 years as an aeronautical engineer, during this time I have had a keen interest in biology and now would like to pursue this as a career. Unfortunately I joined the military straight from school, where I gained very high marks, thus have no higher education. Due to my age and commitments I can't afford to go to university full time so have been considering open uni. Would this be a sufficient starting place? If yes then what advice would you give on future paths to take and if no what would be a better place to begin. I currently work full time as an engineer in mini power stations and renewable energy production but I would love to leave this for a career I would enjoy even if this means a rather drastic pay reduction! I am sure you answer a lot of similar questions but I would appreciate any advice you could give me.
