What Order Should You Take the EASA PPL Theory Exams In? (The Recommended Sequence)
If you have just enrolled in an EASA PPL course, or you are thinking about starting one, you will quickly discover that there are nine theory subjects to pass. That raises a very practical question: in what order should you sit them? This is one of the most common questions asked by student pilots, and for good reason. The order you choose can affect how efficiently you study, how well your theory knowledge supports your flying lessons, and whether you comfortably meet the 18-month completion deadline.
In this article, we will walk through a recommended exam sequence that has worked well for thousands of EASA students. We will explain why certain subjects belong early in your schedule, why others are best saved for later, and how the order connects to the practical flying you are doing in the air. By the end, you will have a clear plan for tackling all nine exams in a logical, stress-free order.

The Nine EASA PPL Theory Subjects at a Glance
Before diving into the recommended order, it helps to know what you are working with. The EASA PPL(A) theoretical knowledge examination consists of nine separate papers, each testing a different subject area. These are: Air Law, Aircraft General Knowledge, Flight Performance and Planning, Human Performance, Meteorology, Navigation, Operational Procedures, Principles of Flight, and Communications. Each exam is a multiple-choice paper with between 12 and 16 questions, and you typically have between 20 and 45 minutes to complete each one, depending on the subject. To learn exactly what is covered in each paper, read our complete guide to the EASA PPL theory exams.
You must pass all nine exams, and your passing mark in each subject is 75%. Once you pass your first exam, the 18-month clock starts ticking. All nine exams must be completed within this period. Understanding this constraint is essential when planning your exam order, because starting too late or spacing your exams too unevenly can create unnecessary pressure as the deadline approaches.
The Recommended Exam Order
There is no single mandatory order imposed by EASA for PPL theory exams. You are free to sit them in any sequence you like, provided you complete all nine within the 18-month window. However, experienced instructors and successful students consistently recommend a phased approach that builds knowledge logically. The general principle is to start with the subjects that are directly required for your early flying, then move to the subjects that support your cross-country and advanced training, and finish with the more technical material.
Phase 1: The Foundations (Air Law and Communications)
There is broad agreement among instructors that Air Law should be your first exam. The reason is straightforward: EASA requires you to have passed Air Law before you are permitted to fly solo. Since your first solo flight typically occurs around the 15 to 20-hour mark, you need to have this exam behind you relatively early in your training. Starting your Air Law study from day one, alongside your first few dual lessons, ensures you will be ready in time.
Communications is the natural partner to Air Law as your second exam. Radio work is one of the first things you will practise in the air, and understanding the phraseology, procedures, and frequencies used in aviation is essential from your very first lesson. The Communications exam is relatively short and straightforward compared to some of the other papers, with 12 questions and a 20-minute time limit. Most students find they can prepare for it alongside Air Law and sit both exams within their first month or two of training.
Sitting these two exams early also starts your 18-month clock promptly, which is actually an advantage. It gives you the maximum possible window to complete the remaining seven subjects without pressure. Some students make the mistake of delaying their first exam for several months, effectively wasting part of their 18-month allowance before they have even started.
Phase 2: The Core Subjects (Human Performance, Meteorology, Principles of Flight)
Once Air Law and Communications are out of the way, the next group of subjects forms the theoretical backbone of your flying knowledge. Human Performance covers how the human body and mind function in the aviation environment, including topics like fatigue, stress, vision, and the effects of altitude. It is a subject that applies to every flight you will ever make, and many students find it one of the more engaging papers because it is directly relevant to your own performance in the cockpit.
Meteorology is widely regarded as one of the more challenging PPL subjects, largely because it requires you to understand and interpret a wide range of atmospheric processes. Weather affects every aspect of VFR flying, from your pre-flight decision-making to in-flight navigation. Studying Meteorology alongside your early flying lessons is highly effective because you can directly observe the weather phenomena you are learning about. A lesson on cloud types is far more memorable when you can look out of the training room window and identify the clouds you just studied.
Principles of Flight explores the physics of how an aircraft flies, covering topics such as lift, drag, thrust, stability, and control. This subject provides the theoretical foundation for many of the manoeuvres you will practise in the air, from straight and level flight to stalls and spins. Understanding why an aircraft behaves the way it does will make you a more competent and safer pilot. Most instructors recommend studying Principles of Flight after you have a few hours of dual instruction under your belt, because the practical experience of feeling the aircraft's responses will make the theoretical concepts much easier to grasp.
Phase 3: The Applied Subjects (Operational Procedures, Flight Performance and Planning, Aircraft General Knowledge, Navigation)
The final four subjects are best tackled once you have a solid foundation from the earlier exams and a reasonable amount of flight experience. Operational Procedures covers the rules and recommended practices for safe flight operations, including pre-flight preparations, emergency procedures, and collision avoidance. There is some overlap with Air Law, which is why studying it after Air Law makes the material easier to absorb. Much of what you learn in Operational Procedures will be directly relevant as you progress towards your solo cross-country flights and your skills test.
Flight Performance and Planning is a highly practical subject that teaches you how to calculate take-off and landing distances, fuel requirements, weight and balance, and cruise performance for different flight conditions. This subject becomes most useful when you are planning your cross-country flights, which is why it is ideally studied in the middle-to-late stages of your training. By this point, you will have enough practical experience to understand why these calculations matter, making the theory far more meaningful.
Aircraft General Knowledge covers the mechanical and electrical systems of a light aircraft, including the engine, propeller, electrical system, and instruments. Some students find this subject dry if they have no engineering background, but it becomes much more interesting when you can relate it to the aircraft you are actually flying. Knowing how your training aircraft's systems work will help you understand your instructor's pre-flight briefings and make you more self-sufficient during your own pre-flight inspections.
Navigation is the natural final subject for most students. It ties together elements from several other papers, including Meteorology (for assessing weather along your route), Flight Performance and Planning (for calculating fuel and time), and Principles of Flight (for understanding wind effects on your track). By the time you reach Navigation, you should have considerable experience with chart reading and route planning from your dual and solo cross-country flights. Many students report that Navigation is one of the most enjoyable exams because it is so directly connected to the practical skill of getting from A to B safely.
How the Theory Order Connects to Your Flying
One of the most important principles to understand is that your theory study and your flight training should not be treated as two separate, unrelated activities. The students who perform best in both areas are those who actively connect what they learn on the ground with what they practise in the air. When you study Meteorology, look at the actual weather forecasts for your next lesson. When you study Navigation, plan a route to the aerodrome you will be flying to. When you study Aircraft General Knowledge, identify the systems on your training aircraft during your pre-flight walkaround.
This connection between theory and practice also works in reverse. After a lesson on stalling, your understanding of Principles of Flight will deepen. After your first solo cross-country, the Navigation exam questions about chart symbols and track calculation will make far more sense. By aligning your theory study with your practical flying progress, you reinforce both simultaneously and reduce the total amount of time you need to spend on each.
Managing the 18-Month Deadline
The 18-month rule is perhaps the most consequential constraint on your exam planning. The clock begins at the end of the calendar month in which you pass your first theory exam, and all nine exams must be completed before it expires. There is no provision for extensions. If you fail to complete all nine within the window, you must retake all exams from the beginning, regardless of how many you have already passed.
To manage this deadline effectively, work backwards from your intended completion date. If you are a part-time student training over 12 to 18 months, aim to sit your first two exams within the first two months of training. This gives you the full 18-month window for the remaining seven. Space your subsequent exams evenly, aiming to complete roughly one exam every six to eight weeks. This pace is manageable for most students who are also flying regularly, and it builds in a comfortable buffer against unexpected delays.

Using a question bank that tracks your progress across all subjects can be invaluable for deadline management. It allows you to see at a glance which subjects you have mastered and which still need work, helping you allocate your study time where it is needed most. Easy EASA's practice exams are structured to mirror the actual EASA exam format, so when your scores are consistently above 80% in the practice environment, you can book your real exam with confidence.
Conclusion
The recommended order for EASA PPL theory exams follows a logical progression: start with Air Law and Communications to support your early flying, move through the core subjects of Human Performance, Meteorology, and Principles of Flight to build your theoretical foundation, and finish with the applied subjects of Operational Procedures, Flight Performance and Planning, Aircraft General Knowledge, and Navigation as your practical experience grows.
This sequence is not the only valid approach, but it is the one most consistently recommended by instructors and successful students because it aligns your theory study with your practical flying, distributes the workload evenly, and ensures you meet the 18-month deadline without last-minute pressure.
