What are the biggest challenges students face in academic writing?

In my opinion, lack of practice is a major challenge in academic writing. Many students do not write regularly, so they find it difficult to express their ideas clearly and effectively. Because of limited practice, they struggle with sentence formation, vocabulary, and proper structure. They may also lack confidence while writing, especially during exams or assignments. As a result, their answers may not reflect their actual understanding of the topic. Regular writing practice helps improve clarity, accuracy, and confidence, but without it, students continue to face difficulties in developing strong academic writing skills over time.
