ADF JOA Numerical study plan

ADF JOA Numerical · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Number Series and Pattern Recognition

Identify and name the five most common series rules (constant difference, constant ratio, alternating, quadratic, prime/fibonacci-style) by working 40 short sequences
Compute next-term and missing-term answers for 30 arithmetic and geometric series without a calculator
Build a one-page rule-identification checklist and apply it to 15 mixed sequences under a 60-second-per-item cap

A scored 30-item series worksheet (target 80%+ accuracy) with each miss tagged to a named rule.

Week 2

Solve 25 two-step pattern items (differences-of-differences, interleaved pairs) and record the rule in one line each
Drill 40 order-of-operations and integer-arithmetic items to build speed on computation
Explain aloud why a chosen pattern fails on 10 near-miss distractors

A timed 20-item mixed series-and-computation quiz completed in 20 minutes with a written error log.

Week 3

Compute 50 multi-digit addition, subtraction, multiplication, and division problems using estimation-first checks
Apply divisibility rules and factor/remainder reasoning to 30 items
Practice 20 fraction and decimal arithmetic items to fluency without a calculator

A 40-item arithmetic accuracy sheet scored at 90%+ with timing noted per section.

Week 4

Convert fluently among fractions, decimals, and percentages across 40 items
Solve 25 percentage-change and successive-percentage problems using a single multiplier method
Set up and solve 20 ratio and proportion problems including part-to-whole and scaling
Solve 15 direct and inverse proportion word items

A 30-item percentages-and-ratios test scored at 80%+ with a one-page formula sheet you wrote yourself.

Week 5

Read 6 self-made tables and extract totals, averages, and differences accurately
Compute percentage share and rate-of-change from 5 self-made bar or line descriptions without a figure
Estimate answers from rounded table values before exact calculation on 20 items
Identify the fastest path to an answer in 15 data-interpretation items

A 15-item data-interpretation set (all data stated in text) scored at 75%+ in 25 minutes.

Week 6

Translate 20 word problems into equations and solve them, showing the setup line
Solve 15 work-rate, distance-rate-time, and mixture problems using standard templates
Solve 15 practical reasoning items involving money, discounts, and averages
Check answers for reasonableness on 10 items by estimating first

A 20-item word-problem set scored at 80%+ with every setup line written out.

Week 7

Convert among metric and common imperial-style units across 30 items
Estimate quantities and round to appropriate precision on 20 items
Complete two full mixed 30-item sets under strict time limits and log per-item timing
Reduce average solve time on your slowest item type by 20%

Two timed mixed practice sets with a timing log showing average seconds per item and accuracy per domain.

Week 8

Take three full-length timed mock exams and score each by domain
Re-drill only the two weakest domains until each reaches 85%+ on targeted practice
Review every logged error and rewrite the correct method in your own words
Finalize a 5-minute pre-exam checklist covering pacing and estimation habits

A mock-exam score tracker across three attempts showing improvement and a final error-review sheet.

Week 2: Score 80%+ on a 30-item series-and-pattern set in 30 minutes.

Week 4: Score 80%+ on a 30-item percentages-and-ratios test and produce a complete self-written formula sheet.

Week 6: Score 80%+ on a 20-item word-problem set with all setup lines shown.

Week 8: Score 85%+ overall on the final full-length mock with no domain below 75%.
