This study aims to get an overview of the implementation of lectures in General Biology in the Chemistry Education FKIP Unsri. The sample of this study was Chemistry Education students in the 2018/2019 academic year (n = 43). The instruments used were documentation studies to find out the achievements of students in general Biology courses and survey questionnaires to find out the concepts that were considered the most difficult, the causes of difficulties understanding the concepts, and the interest of students in the quiz held before learning. The data shows that the achievement of student learning results shows 57.45% of students are still in the "C" and "D" assessment categories. Meanwhile, the concept of human physiology (41.86%) and cells (structure, metabolism, and reproduction) (39.53%) is the most difficult concept for students to understand. The difficulty of understanding this concept is due to the large number of uses of terminology (72.1%) and the weakness of students initial knowledge from previous levels of education (51.2%). These findings indicate the importance of diagnostic tests before the lecture is done so that the lecturer knows more about the weaknesses and strengths possessed by students so that the lectures that take place become more directed.
