Difficult to say without more context tbh. Depends why you failed the exams. If it was because you struggled with the topics, how do you know you would be able to pass 1st year next time round if you do get into Medicine again? If it was because you struggled with motivation, maybe Medicine isn’t the best career option for you. I’m not discouraging you from applying again but after being kicked out, it’s a good time to ask yourself whether Medicine is still what you want to do. Are you prepared to give up more years of your life to do another degree AND 5 years of medical school?
Having said that, being kicked out of medical school in the UK puts your next application at risk. I won’t lie to you: it’s unlikely you will be accepted for Medicine again in the UK. The system is closed to students who have previously withdrawn from any UK medical school due to failing exams.
My advice to you would be to look at your options for studying Medicine abroad. If Medicine is still what you want to do, you can save yourself a couple of years and the high competition of Graduate Entry by studying in another country. There are plenty of places in Eastern Europe taking on British students who either don’t get into Medicine in the UK or have failed somewhere already. I would consider this if I was in your position.
