TOGAF, in Series or in Parallel ?

When becoming TOGAF certified you at some point be faced with the dilemma of either taking the two TOGAF exams in series, i.e. the Foundation OG0-91 exam followed by the Certified Exam OG0-092 some time later, or taking the combined Part 1 and Part 2 Exam OG0-093 to achieve Level 2 certification directly. If like me you are paying the certifications yourself then the financial implications will need to be taken into account, since taking the exams individually costs approximately 25% more.

In the UK each individual exam works out at around £195 each and the combined exam is £301. So by taking the combined exam you can make a saving of £89. But there is a catch, if you fail either of the two parts of the combined exam you don’t receive any credit for the other part you passed!

However, the saving of £89 was significant for me, so I took the combined exam and found that part 1 was in fact a good warm-up to part 2. Part 1 is significantly easier than part 2 and I would be amazed if anyone who took the combined exam failed part 1 but passed part2.

So in summary my advice would be:

  • If cost is an issue, and level 2 certification is your goal, then wait until your study has achieve the standard required by the level 2 certified exam and then take the combined exam.
  • If cost isn’t an issue (for example, your company is paying for the exams) then take them in series, why give yourself more pressure than you need and you can build your confidence by passing the Foundation exam first.
  • If you can pass the Certified (Part 2) exam then you will find the Part 1 Foundation questions easy.
  • There is plenty of time in the combined exam and I personally didn’t find doing a two part exam in one go a problem, if anything the part 1 exam was a good warm-up for what was to come in part 2.

Exam tips for the TOGAF 9 Foundation Exam

TOGAF CertificateHaving recently passed the TOGAF 9 Exams I thought I would share with you some general tips which you may find helpful if you decide to take the exam yourself:

  • Arrive at least 20 minutes early for the exam to allow time for traffic or difficulties in parking: you can then use this time to go over any last-minute revision for areas.
  • The Foundation Exam is closed book so you will not be allowed to take anything with you into the testing area, but you will be given a blank sheet of paper and a pen. You should use the time before the exam starts to note anything down for areas you have a hard time remembering. It is a good idea to write down all of the phases of the ADM and the corresponding descriptions of these phases.
  • The Foundation Exam is only 60 minutes long, so use your time wisely and work through the questions methodically. If there is a question you cannot answer, leave it and come back later. The Foundation Exam has 40 questions so plan accordingly to make sure you don’t run out of time and check your watch in the exam after every 10 questions to keep on track (10 questions = 15 minutes).
  • In the words of Douglas Adams Don’t Panic!. Just work through the exam methodically and diligently. There is enough time if you are prepared and the majority of questions straight forward and not designed to trick you.
  • Don’t make assumptions or jump to conclusions. Make sure you read the questions thoroughly and all of the possible answers. Re-read the question to make sure you know what is being asked before answering.
  • For questions that you are not confident, mark them and come back to them later if you have time. Working through other questions will sometimes jog your memory and you will find an earlier question easier to answer later.
  • Use a process of elimination to remove obviously incorrect answers. This approach allows you to concentrate on the probable answers.
  • Don’t leave any questions unanswered at the end of the test. There are no points deducted for a wrong answer, so answer all questions. Make an educated guess and you may just pick the correct answer.

Best of luck.
