Diagnose baseline accuracy and pace in numerical reasoning by completing 30 untimed percent, ratio, and rate problems and logging every error by cause

Build a one-page formula sheet covering percentages, ratios, averages, and unit conversions, then solve 20 problems using only that sheet

Practice verbal passage mapping on 6 short passages, writing a 3-line structure summary before answering any question

Establish a timed practice routine of three 20-minute sessions per week with a stopwatch log

Drill percentage change, compound growth, and reverse-percentage problems until 85% accuracy on a 25-question set

Interpret tables and bar charts under a 90-second-per-question limit across 4 timed sets

Identify the four most common verbal question stems (main idea, inference, detail, author tone) and write a decision rule for each

Eliminate two answer choices per verbal question before selecting, tracking how often the surviving pair contains the correct answer

Classify rotation, reflection, and series-progression patterns across 40 abstract figure items and name the rule used for each

Complete 60 spatial reasoning items involving 2D net folding and cube rotation, sketching the fold for any missed item

Apply estimation shortcuts (rounding, fraction benchmarks, digit-sum checks) to 20 numerical problems to cut calculation time

Review the week 1-2 error log and re-solve every missed numerical item without notes

Solve 30 mechanical comprehension items on levers, pulleys, gears, and mechanical advantage, writing the governing relationship before calculating

Practice 8 work-sample judgment scenarios by ranking response options and justifying the top and bottom choice in two sentences each

Complete two full-length timed mixed sets of abstract and mechanical items and record pacing splits per section

Redo all missed abstract items from week 3 and confirm each rule is now recognized within 45 seconds

Master gear-train, belt-drive, and pulley-system direction and speed problems to 90% accuracy on a 25-item set

Analyze fluid pressure, simple circuits, and basic tool-use items, writing a one-line principle for each missed question

Complete 6 work-sample scenarios under time pressure, prioritizing safety, procedure compliance, and escalation before speed

Drill 40 spatial items mixing net folding, mirror images, and hidden-shape identification

Read 10 dense passages under a 3-minute limit and answer 4 questions each, targeting 80% accuracy

Practice inference and assumption questions specifically, writing the logical gap bridged by the correct answer for 15 items

Review work-sample judgment priorities and resolve 10 scenarios where two options both seem reasonable, documenting the deciding criterion

Revisit mechanical items missed in week 5 and re-solve them cold

Complete three full timed numerical sections with strict per-question caps and no unanswered items

Complete three full timed abstract sections, guessing-and-flagging rather than stalling on any single item

Simulate two full mixed exams of all four domains back to back to build stamina

Audit the error log for recurring patterns and write a pre-question checklist for each domain

Take two final full-length timed simulations under exam conditions and score each domain separately

Re-solve every item still flagged as unresolved across weeks 1-7

Rehearse pacing rules for each domain, including when to skip, flag, and return

Reduce the formula and principle sheets to a single final review card memorized cold
