Read as much as you can. There are no good writers out there who are not also good readers. You will learn more advanced words, sentence structures, writing styles, etc. Try reading different types of sources too, I.e. The official news is written differently than certain articles. Find something you enjoy and read about it.
You can also try joining forums or certain social media and practice sharing your views through writing. By this I do not mean Twitter. There are even political/religious forums on JSP where people have discussions. Look up different forums, online websites (for their comment sections) and media.
You could write for fun. Pick topics you are super interested in and practice writing a couple paragraphs to a couple pages about them. Learn how to find and cite good sources.
This is very important. A few more tips.
As you will likely learn in college, you will probably be able to access your schools storage of resources online, cites they have subscribed to which have all sorts of different essays and journals which are peer reviewed. These are very important if you are doing any sort of research paper for any sort of topic it may be on.
