The document discusses common mistakes students make when writing research papers, including not writing a literature review, placing content in the wrong sections, making probabilistic claims without evidence, improper use of singular/plural verbs and helping verbs, incorrect use of "either" vs "both", saying "comprised of" instead of just "comprised", omitting hyphens in compounds like "internet-based", using uncommon words unnecessarily, incorrect pluralization of words like "equipment", and using tautologies. The author provides examples of each mistake and recommends best practices to avoid these issues.
