Technology classes.
I don't know what a "technologist" is. You need to be more specific. However, in general, for a technical job in any given field you take courses in that field ... and probably a lot of others. There really isn't a specific standard curriculum (set or courses you take) that's the same everywhere; you would do best to determine what degree is required for the specific job you're thinking of, and then going to some college websites to see what courses they require for that particular degree.
You'll need to take premed courses in college before you can become a surgical technologist. The best High School Courses to help you prepare for that are math and science classes, especially the more advanced biology courses.
You need to take the classes specified by the school's radiology department. Here's an example of the radiological technologist curriculum at St .Lukes http://www.stlukescollege.edu/body2.cfm?id=61
You will need to take a curriculum developed towards obtaining a degree in veterinary technology - there are many colleges around the United States that offer this.
In high school you should start by taking health, math, biology, and chemistry classes to help you get a job in this field later on. You must have your CST certification and must complete multiple training classes.

In order to become a full- or part-time MRI technologist, you'll first need to take some classes and earn your MRI technologist degree. You can do this at a variety of health care programs by earning your MRI technologist certificate and two- or four-year degrees. Once you've completed your program you can become officially certified by ARMRIT by taking the MRI technologist certifying exam. The higher your degree, the more chance you will have at getting a higher-paying job.
No, there are no online surgical technologist school. However, you can take basic biology classes online to prepare for the program.
There are no math classes you need to take to become a wedding planner. You don't need certain training or a specific degree. There are wedding planner classes you can take, but they are not heavy in math.
