PPL theory in 18 months: a realistic week-by-week study plan
Nine EASA subjects, hundreds of hours of material and a strict 18-month exam window. For many PPL students it feels like a mountain. But with a well-structured study plan it is a completely manageable journey. This article gives you a concrete, week-by-week approach to comfortably passing all 9 subjects within the window.
Step 1: understand the 18-month window
The EASA 18-month window starts automatically on the date of your first approved exam — even if that is an easy subject. From that moment you have 18 calendar months to complete all remaining subjects. Plan your exams deliberately: take your first exam only when you already have several subjects ready, or when you are confident you can finish the rest within the window.
Practical rule: you need on average 2 months per subject at 6–8 study hours per week. Nine subjects × 2 months = 18 months — exactly the window. There is no slack for delayed exams.
Step 2: sort subjects by difficulty
Not all subjects are equally demanding. Start with accessible subjects to build momentum quickly, and save the heavier ones for when you are in the rhythm.
Easier: Human Performance (040), Communications (090), Operational Procedures (070) Medium: Meteorology (050), Air Law (010), Principles of Flight (081) Harder: Navigation (061), Aircraft General Knowledge (021), Performance & Planning (032)
Start with Human Performance: it is manageable, gives you an early pass on the board, and you can open the window without putting another subject at risk.
Step 3: commit to 6–8 hours per week
Six to eight hours per week is the minimum for comfortable progress. Spread this over multiple sessions: two or three blocks of 2–3 hours per week is more effective than one long Saturday of eight hours.

Step 4: do weekly practice exams
From week 3 of each subject: practise with multiple-choice questions at EASA level. Summarising helps with understanding, but practice exams are the only thing that tells you directly whether you are ready to sit the real thing.
Rule of thumb: if you score above 80% for two consecutive weeks in practice exams, you are ready for the real exam. Scoring consistently 65–74%? Book a tutoring session before the exam, not after.
Step 5: keep one month as buffer
Keep the final month of your 18-month window free as a buffer. This is your safety margin for illness, busy work periods or an unexpectedly difficult exam. Those who do not need the buffer have earned it. Those who do need it are glad it is there.
Do not schedule exams in the final two weeks of the window unless you already have everything done. Planning stress leads to poor performance.
Example: an 18-month schedule
Months 1–2: Human Performance · Months 3–4: Communications · Months 5–6: Operational Procedures · Months 7–8: Meteorology · Months 9–10: Air Law · Months 11–12: Principles of Flight · Months 13–14: Aircraft General Knowledge · Months 15–16: Navigation · Months 17–18: Performance & Planning + buffer
This schedule assumes 6–8 study hours per week. Have more time? Compress to 12 months by doing two subjects simultaneously (never more than two). Have less? Take a longer trajectory and open the window as late as possible.
