First thing, do your best in high school to achieve good grades so that you may be eligible for a partial or full scholarship. I also recommend getting your associates degree from a community college instead of jumping right into a four year college or university. You can save lots of money during those first 2 years and also expose yourself to science classes to see if you really are interested in this career path without spending as much money to do it. After 2 years, if you have gotten good grades, you may be eligible for a scholarship to get your bachelors degree at a college or university. Additionally, make sure you understand how much debt you are taking on. When you initially sign up for loans through the financial aid office, most people don't think much about it because they don't have to pay it off yet. Make sure you are comfortable with how much debt you will have in the future.
