| Problem | Quick Fix | |--------|------------| | Balancing redox reactions in acidic/basic medium | Memorize the half-reaction method step-by-step pattern. Practice 10 problems in a row. | | Le Chatelier’s principle (direction of shift) | Ask yourself: “What would the system do to oppose the change?” – then apply. | | Calculation of pH for weak acids/bases | Write the dissociation equation first, then the Ka/Kb expression, then solve. Never skip writing the equation. | | Organic nomenclature (IUPAC names) | Make flashcards of prefixes (meth-, eth-, prop-, but-) and suffixes (-ane, -ene, -ol, -oic acid). | | | Le Chatelier’s principle (direction of shift)

💡 Don't just copy the answers. The Sudanese Certificate often asks you to explain the reasoning behind a chemical reaction, not just the final product.
