I got some information from http://people.howstuffworks.com/becoming-a-doctor.htm -it's a great website for information on becoming a doctor of all sorts! I would suggest anyone thinking of becoming a doctor to check out that website for more details. But here is the basics: First, you need to go to college and get VERY good grades. The requirements for most medical schools are: 1 year of Biology with lab 1 year of Inorganic Chemistry with lab 1 year of Organic Chemistry with lab 1 year of English Many schools require 1 year of calculus or college level math Some medical schools request a course in Biochemistry. Since Pre-Med is not a major, it is common for pre-med students to major in Chemistry or Biology. Any college that offers premedicine will have an advisor who can also help you out in terms of looking at medical schools. You also have to take the MCATS which are Medical College Admissions Test. Once you get into Med School, you have to take the Boards your 2nd year. You will take the 2nd part at the end of your 4th year, and the 3rd part in the first year of residency. After Med School you will pick a field to specialize in. This is where you would choose to specialize in Cardiology. You would then complete your fellowship after your residency. A Pediatric Cardiologist would require an additional 2-3 years after the 3 year residency. After that, you must get a medical license so you can practice medicine. After that, you must be board certified. THEN, you get a job! Easy enough, right? (Sarcasm) SO, to answer your question, you will be in medical school for 4 years. But if you add up college (4 years), medical school (4 more), Residency (3 years) Fellowship (2-3 more); that equals 13-14 years of schooling/training. It's a very long process, as I'm sure you already know that =) According to Salary.com, in Dallas, TX, the average Pediatric Cardiologist makes $259,109 a year. In TX, I found 1 Medical School in Dallas and it is the University of Texas Southwestern Medical Center at Dallas Southwestern Medical School. I posted a link (the last one) to a list of all the medical schools in Texas. Good luck with your future! After all that, that's why I'm a Nursing Major =)
