SOF IEO study plan

SOF IEO · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

English language and comprehension (word order, conditionals, modals, collocations, phrasal verbs, idioms, language and people)

  • Diagnose baseline accuracy by completing one 40-item mixed grammar and vocabulary set under timed conditions and logging every error by type (word order, conditionals, modals, collocations, phrasal verbs, idioms).

  • Classify 60 phrasal verbs into particle patterns (up/down, in/out, on/off, through, over) and write one original sentence for each verb in a context a working adult would plausibly meet.

  • Rewrite 20 scrambled sentences so that adverbial placement, inversion after negative openers, and adjective order follow standard written English, then justify each reordering in one line.

  • Build a personal error log template with columns for item, rule violated, corrected version, and re-test date, and populate it with week 1 errors.

Your checkpoint

A dated error log containing at least 60 phrasal-verb sentences and 20 corrected word-order items, with each entry tagged to a named rule.

Week 2

English language and comprehension (word order, conditionals, modals, collocations, phrasal verbs, idioms, language and people)

  • Contrast all four conditional types plus mixed conditionals by transforming 25 base sentences into each type and labelling the time reference and modal nuance of the result.

  • Distinguish modal meanings (obligation, deduction, permission, ability, hypothetical) by matching 30 short workplace-style utterances to their function and rewriting five ambiguous ones for clarity.

  • Memorise and apply 40 high-frequency collocations by grouping them by verb or noun head and using each in a two-clause sentence.

  • Self-test conditionals and modals from memory for 20 minutes, then re-teach any rule you missed aloud in under 60 seconds.

Your checkpoint

A 25-item conditional transformation sheet plus a 30-item modal-function key, both scored and annotated with corrections.

Week 3

English language and comprehension (word order, conditionals, modals, collocations, phrasal verbs, idioms, language and people)

  • Interpret 15 idioms and phrasal verbs from context alone, without a dictionary, and record the contextual clue that unlocked each meaning.

  • Explain how register, idiom choice, and directness shift between formal writing, workplace email, and casual conversation by rewriting the same message in three registers.

  • Analyse language-and-people scenarios (politeness, euphemism, ambiguity, cultural connotation) by answering 15 short-response prompts and defending each choice in two sentences.

  • Reduce idiom errors by re-testing the week 1 set and targeting only items still missed.

Your checkpoint

A three-register rewriting portfolio of one message plus a 15-item idiom-in-context answer key with justifications.

Week 4

English language and comprehension (word order, conditionals, modals, collocations, phrasal verbs, idioms, language and people) & Problem-solving and critical thinking tasks in English

  • Complete a full timed domain 1 mock (grammar, vocabulary, comprehension) and compute accuracy by subskill to identify the two weakest areas.

  • Practise comprehension under time pressure by summarising three 300-word passages in exactly 40 words each and checking that no key claim is dropped.

  • Apply a four-step problem-solving routine (restate, list constraints, test cases, verify) to five logic puzzles and label which step consumed the most time.

  • Write a one-page diagnosis of your error patterns and convert it into three corrective drills for week 5.

Your checkpoint

A scored domain 1 mock with a subskill accuracy table and a written diagnosis naming the two weakest subskills.

Week 5

Problem-solving and critical thinking tasks in English

  • Solve 20 verbal-reasoning items (analogies, odd-one-out, syllogisms, ordering) and record the reasoning rule used for each in a single line.

  • Separate valid from invalid inferences by evaluating 15 short arguments and marking the exact premise that fails.

  • Build truth tables for five conditional and biconditional statements and use them to test whether a given conclusion follows.

  • Set a 90-second-per-item ceiling and practise abandoning and returning to stalled items without losing accuracy elsewhere.

Your checkpoint

A 20-item reasoning log with a stated rule per item and a timed accuracy score at the 90-second ceiling.

Week 6

Problem-solving and critical thinking tasks in English

  • Solve 15 data-interpretation and quantitative-reasoning sets (ratios, percentages, averages, rates) and show a one-line estimation shortcut for each.

  • Detect assumptions and flaws in 15 short arguments by naming the unstated premise and describing one counterexample.

  • Complete three 25-minute mixed critical-thinking sets and track accuracy against time to find your speed-accuracy trade-off point.

  • Re-derive every formula you used from first principles so no step depends on memorised shortcuts alone.

Your checkpoint

A formula-and-shortcut sheet with 15 worked data sets and 15 named argument flaws, all self-checked.

Week 7

English language and comprehension (word order, conditionals, modals, collocations, phrasal verbs, idioms, language and people) & Problem-solving and critical thinking tasks in English

  • Sit two full-length timed mocks under exam conditions and record per-section timing splits.

  • Review every wrong answer to root cause (knowledge gap, misread, time pressure, careless slip) and tag each accordingly.

  • Drill only the top three root causes with 30 targeted items each until accuracy exceeds 80 percent.

  • Rehearse a fixed section-order and time-budget strategy and confirm it holds across both mocks.

Your checkpoint

Two completed full mocks with a root-cause tally and a written timing strategy that shows improvement between mock one and mock two.

Week 8

English language and comprehension (word order, conditionals, modals, collocations, phrasal verbs, idioms, language and people) & Problem-solving and critical thinking tasks in English

  • Re-test the full error log and confirm that at least 85 percent of previously missed items are now correct.

  • Complete one final timed mock and compare subskill accuracy to the week 4 baseline to quantify gains.

  • Consolidate a one-page rule sheet covering conditionals, modals, word order, and the four-step reasoning routine for last-minute review.

  • Plan a light two-day pre-exam routine that avoids new material and protects sleep and timing rhythm.

Your checkpoint

A one-page consolidated rule sheet plus a baseline-versus-final accuracy comparison showing measured improvement.

Milestones

Week 4: Domain 1 mock completed under time; subskill accuracy table shows at least 70 percent overall and the two weakest subskills are named in writing.

Week 6: Twenty reasoning items logged with a stated rule each, and timed accuracy on mixed critical-thinking sets is at least 65 percent.

Week 7: Two full mocks done; mock two total score exceeds mock one, and every wrong answer carries a root-cause tag.

Week 8: At least 85 percent of error-log items are re-tested correct, final mock beats the week 4 baseline, and the one-page rule sheet is complete.
