The OFA 2 and OFA 3 exams each have two parts to them: the written portion and the practical portion. A common misunderstanding is that each portion of the exam is a separate exam by itself. That is, everyone tends to refer to a written exam and a practical exam for the OFA 2/3.
In order for a student to pass the OFA 2/3 exam, the student must pass the written portion and the practical portion together. If the student pass the written portion, but fails the practical portion (or vice versa), the student failed the entire OFA 2/3 exam.
Every time a student takes the OFA 2 or OFA 3 class, the student has two attempts to pass the exam. So if the student fails the first attempt at the exam, the student has a second attempt. The student can sit in on existing classes (if space is available) for certain lessons as review before the second attempt. The student has to re-do both the written part and the practical part - even if the student had passed one of those parts on the first attempt.
If the student fails both attempts (i.e. fails twice), the student has to take the whole OFA 2/3/ course again.
Below is a matrix regarding the students results and outcomes:
| Exam Attempt | Written Portion | Practical Portion | Final Result | Outcome |
| 1st | Pass | Pass | Pass | Certified |
| Fail | Fail | Fail | Can try exam again | |
| Pass | Fail | Fail | Can try exam again - must re-do written and practical | |
| Fail | Pass | Fail | Can try exam again - must re-do written and practical | |
| 2nd | Pass | Pass | Pass | Certified |
| Fail | Fail | Fail | Take the whole course again | |
| Pass | Fail | Fail | Take the whole course again | |
