Thank you for sending this! This "Scheme of Work" is exactly what we need. It clearly outlines the key topics for Chemistry. Based on this list and your identified weakness in Chemistry, let's start with a foundational topic that is crucial for understanding almost everything else: Topic: Atomic Structure and Electronic Structure (from points 1 and 2 on your list) This includes: Atomic Theory Periodic Table Electronic Structure (electron configuration) Here's how to approach this topic efficiently, without getting lost in bulky PDFs: Step 1: Targeted Past Question Review Go through your CHM 101 and UTME Chemistry past questions. Find all questions related to: Atomic models (Dalton, Thomson, Rutherford, Bohr) Subatomic particles (protons, neutrons, electrons) and their properties Atomic number, mass number, isotopes Periodic trends (electronegativity, ionization energy, atomic radius) Electron configuration (e.g., 1s^2 2s^2 2p^6) Quantum numbers (if covered in CHM 101) Step 2: Focused PDF Reading Now, open your Chemistry PDF notes. Go directly to the sections covering "Atomic Structure," "Periodic Table," and "Electronic Structure." Do not read everything. Focus on: Definitions: What is an atom? What are isotopes? What is ionization energy? Key Concepts: How do electrons fill orbitals? What are the rules (Aufbau, Hund's, Pauli exclusion)? How do periodic trends change across a period and down a group? Examples: Look at examples of electron configurations for different elements. Understand how to determine the number of protons, neutrons, and electrons from atomic and mass numbers. Step 3: Practice and Self-Test Work through the past questions you identified in Step 1. Try to solve them without looking at your notes first. If you get stuck, refer back to the specific section in your PDF notes. Let's begin with a specific concept from this topic. Question: What are the three main subatomic particles, and what are their relative charges and locations within an atom?
