I’m not an expert but I believe that you can try applying to chosen ambitious universities and there’re all chances for success. However, you need to polish your profile! No extra curricular? It’s not a huge problem. Focus on your strengths, exceptional personal qualities, skills, and ambitions. Have work experience? Great! Add this to your profile! Worked on a research project? Awesome! Don’t forget to mention it either. So, your task here is to show that you’re truly ambitious, enthusiastic and ready to take on any challenges you may face while studying at chosen university. Wish you all the best luck!
