Chemistry course helped me to refresh my knowledge in basic chemistry after years of my education. The teachers are great - Dr Allison Soult and Dr Kim Woodrum. The course takes you through the concepts of atomic structure, periodic table and trends, bonding, stoichiometry and thermochemistry. The teachers have been able to present the topics in a very interesting way. This 10 weeks course will be a great help to students, particularly those who are weak in the subject, to develop an interest and refresh their knowledge before joining a serious course of study in Chemistry. Practice problems help learners to test the understanding at each stage of learning.
