You could also say: I am Muslim. You are not a thing like a pen so you don't have to add "a" in front of Muslim. However if you want to say that you are Muslim as a man you can say: I am a Muslim man. But I would recommend the easier one: I am Muslim. :) Another option for "In front of me one year in high school then go to college." would be: I have one more year of high school ahead of me, then I will go to college. you use "in front of me" to talk about something or someone being in front of you physically. Example: My friend walked in front of me. or There was a table in front of me. While if you want to talk about a period of time that you are aware will be in your future you use -> ahead. Another option for: "I wish so badly to study medicine and become a doctor and serve my country. " could be: I would like to study medicine and become a doctor. That way I can serve my country. Hope this was helpful. All the best.
