How to become a biochemist
Get a good foundation in the sciences.
In high school, you should take classes in all the sciences that you can, especially the natural and physical sciences (like biology and chemistry). These classes will function as the basis of your professional learning in the future and will prepare you to begin your degree in biochemistry once you start learning at the university level.
All science-related fields will be helpful at this point. Make sure you take biology, chemistry, physics, zoology, microbiology, organic chemistry, and any other science-related classes you're able to take.
