This study thought to investigate whether English grammar taught to undergraduate students in Tanzania helps them write well. 120 students were drone from one university and subjected to a writing test before and after grammar training. Thereafter, their texts were evaluated using rubrics, and scores analysed using Paired T-Test. The overall analysis reflected that there is a significant difference (t (119) = - 4.398, p<0.05). However, this does not mean each grammatical item is statistically significant. A slight / no difference was realised on some grammatical items. The study recommends instructors to put much effort on all the grammatical components, but with a special focus on sentences construction and punctuation skills, tenses, linking signals and paragraph crafting, since these are the areas which the study showed that students have serious weaknessesenDiscourseIntensive GrammarLearningESL1/EFL StudentsArticle
