<p>I honestly no longer remember what those career tests told me. They didn’t really influence my decision in choosing a major/career path in college in the end. </p>
<p>Many people change majors at some point in their college years. (I didn’t though)</p>
<p>When your son gets to college and is scientifically inclined, encourage him to find and join a research project, especially through some sort of freshmen/undergrad research program. Many people participate in this, so it isn’t too special, but research projects can certainly do a good job of helping you pinpoint your interests. (It did for me!) I think those programs are a great time investment - built into tuition as well!</p>
