IB Chemistry HL study plan

Map the Structure syllabus (atomic theory, periodicity, bonding, energetics) into a one-page checklist and rate each topic 1-5 on confidence

Derive electron configurations for elements 1-40 and the ions of period 4, then explain anomalies in Cr and Cu from orbital stability

Explain periodic trends (atomic radius, ionization energy, electron affinity, electronegativity) in terms of effective nuclear charge and shielding, with 3 examples each

Classify bonding in 15 given substances as ionic, covalent, metallic, or intermolecular-dominant, justifying each in one sentence

Draw Lewis structures, assign VSEPR shapes, and predict bond angles and polarity for 20 molecules including lone-pair and multiple-bond cases

Apply hybridization and sigma/pi bonding descriptions to explain ethane, ethene, ethyne, and benzene

Calculate enthalpy changes using Hess's law, formation enthalpies, and bond enthalpies, and state when each method fails

Interpret a Born-Haber cycle for an ionic compound and identify which term dominates lattice enthalpy

Balance redox half-equations in acidic and alkaline media and calculate cell potentials from standard electrode data

Predict spontaneity from E-cell and reconcile it with Gibbs free energy using delta-G = -nFE

Explain factors affecting reaction rates using collision theory and sketch Maxwell-Boltzmann distributions at two temperatures

Derive rate expressions from concentration-time and initial-rate data and determine reaction order graphically

Apply Le Chatelier's principle and the equilibrium constant to predict shifts, and calculate Kc and Kp from equilibrium data

Calculate pH, pOH, and buffer behavior for strong and weak acids and bases, including titration curve sketches

Explain entropy and spontaneity qualitatively and calculate delta-G from delta-H and delta-S at non-standard temperatures

Revisit the weakest Structure topics flagged in week 1 and close at least three gaps

Design a full internal assessment outline: research question, background theory, variables, and method, with a risk assessment

Select appropriate apparatus and justify uncertainty, precision, and significant figures for each measurement

Distinguish systematic from random error and describe how to reduce each in a titration and a calorimetry experiment

Produce a data-processing plan that includes error propagation and a suitable graphical treatment

Analyze a provided dataset: calculate means, uncertainties, and percentage error, and plot with correct error bars

Evaluate an experimental procedure against IA criteria and write specific improvements rather than generic ones

Interpret qualitative observations (color changes, precipitates, gas evolution) to identify ions in solution

Explain how to calibrate and use common instruments (burette, balance, colorimeter, pH meter) and their typical uncertainties

Choose one optional topic and build a concept map covering every syllabus point in it

Solve 15 exam-style questions from the chosen option, including at least 3 data-based or synthesis questions

Connect the option back to core Reactivity content where the syllabus links them

Review the Reactivity error log from weeks 2-4 and redo every previously missed calculation type

Sit two full-length timed mock papers under exam conditions and score them against mark schemes

Rank remaining weak topics by marks lost per hour of study and address the top five

Rehearse command words (state, describe, explain, deduce, evaluate) by rewriting answers to match the required depth

Consolidate one master formula and definitions sheet covering all domains
