Here are some ways you can strengthen your writing skills:
Read and write frequently. Read as much as you can from a variety of sources, including plays, essays, fiction, poetry, news stories, business writing and magazine features.
Become familiar with current issues in society and develop your own opinions on the issues. Think of arguments you would use to convince someone of your opinion. Taking speech and debate classes can help you think through issues and communicate them to others.
Practice writing in different formats and in as many real situations as possible. Write letters to the editor, or letters to a company requesting information.
Try some writing in extracurricular activities. School newspapers, yearbooks, and creative writing clubs offer opportunities to express ideas in writing.
Share your writing with others and get feedback. Feedback helps you anticipate how readers might interpret your writing and what types of questions they might have. This can help you anticipate what a reader might want to know.
Learn to see writing as a process—brainstorming, planning, writing and then editing. This applies to all writing activities.
Listen to the advice your English teacher gives you about your writing.
Strive for your writing to be well developed and well organized, using precise, clear and concise language.
Remember that everyone can improve writing skills. Confidence and skill will grow with the more writing you do. Practice and work lead to achievement.
