Hi everyone

Just passed OMG UML Fundamentals exam today. I scored 61 out of 80 questions (passing score : 46 ).

I found the exam time challenging compared to other certification exams. The main hurdle was the scarce resource for preparation (sample questions).

I had only a minimal prior hands-on experience of UML.

My recommendation: read the UML 2.0 specs (I read this recommendation in a thread in this forum, and THAT made me pass !). The exam is not about UML modelling - it's about the elements of the UML.

Besides, I used the following books:

- Larman - Applying UML and patterns (great book for learning UML, but does not bring much for the exam preparation).

- Fowler - UML Distilled (same remark).

- (only in German): Weilkins, Oestereich: UML 2 Zertifizierung (dpunkt Verlag, ISBN 3-89864-294-1 (Great for exam preparation - but basically identical to the UML 2.0 Specs, so if you don't read German, reading the specs will do it.)

Good luck !

Congratulations - good score!

I had a similar experience with time pressures during the test. I didn't have enough time to review the majority of my answers.

Gratuliere und thanks for the info.
I notice UML 2 -Zertifizierung is for sale at amazon.de:

Hi,

I'm also planning to get OMG UML certified, but I'm wondering at what level the questions are asked. Is it (1) theoretical, "What is the definition of an association relationship?", (2) practical, "With what kind of UML relationship would you model the relationship between a car and its engine", or concerning the UML (3) metamodel, "Is an UML generalization relationship derived from an association relationship in the metamodel", or....

I'm quite familiar with the UML diagrams and concepts, but I want to know if I should study the metamodel or just the formal UML definitions of the involved concepts.

Many thanks in advance!

BTW, I think it's a shame that OMG does not provide more information about the scope of the exams, not even a single sample question, although sample questions are announced "coming soon" on the website for over a year!

Andy,

I've got the OCUP Fundamental exam scheduled for Monday afternoon and, although I have been using UML extensively for a number of years, I too am worried about what the certification is aimed at. If it is actual modelling I feel confident for the first exam but if it is regarding the metamodel I would be worried - probably more worried about wasting my money because unless you are going off to create UML tools the metamodel is not really relative to an architects role. We obviously use the abstraction of the metamodel not the model itself.

Has anyone taken this exam and confirmed what it is aimed at; metamodel or modelling concepts?



Regards,

Just an update in case anyone else is thinking about going for the OMG-100 OCUP Fundamental level certification.

Although the exam is not specifically about the metamodel it does relate to it and most of the information regarding usage of the metamodel can only be easily located within the superstructure specification. The problem with the superstructure specification is that it contains alot of metamodel content but it is difficult in the exam not to ignore it.

Anyway, I passed the exam with less than eight hours of studying the superstructure specification but with about eight years extensive experience of UML. I have to admit, had I studied harder I would no doubt have been more confident and less tired at the end of it. It is a hard exam if not studied extensively. What is worrying is that although I had eight years or more experience of UML, I could have failed simply because I did not understand certain aspects of the metamodel. The objective of the exam is "work with commonly encountered UML elements, create simple UML diagrams, and qualified to be member of a UML development team".

It is very difficult to decide whether or not studying and achieving towards the certification has made me a better modeller! As architects we have to understand a whole range of concepts, methodology, standards and technology and therefore have to abstract some of the information in order to cram it all in! I don't think I needed to know the aspects of the OCUP Fundamental Level to make me a better UML practioner - that could have been achieved by refreshing my knowledge with a good UML book (e.g. like the new UML User Guide for UML 2.0).

Still, it's nice to pass it - and it will be on my CV - so, I suppose it was kind of worthwhile.

First of all, congratulations!!!

Secondly, thank you very much for the information about the exam.

Before considering the OCUP exam, I think I'll work towards SCEA and the like first.

The SCEA is a much more challenging prospect and more importantly uses UML in context of an assignment and a development methodology. As part of the SCEA, the author has to determine the best possible presentation of the architecture and design constraint by the very specific requested deliverables. I supplemented my assignment with numerous other UML diagrams to provide different perspectives of the solution, whether or not the assessors took these diagrams into consideration I don't know but it made me feel better and allowed me to understand the overall model much more. There are a lot of decisions to be made in the SCEA and quite a few deliberate contradictions and errors in the requirements that requires the author to make a number of important architectural and design decisions. Ultimately, all this must be presented in at least seven UML diagrams. Create the diagrams using a personal undocumented version of UML notation or incorrect notation and the overall score will be reduced significantly, which will probably result in a fail.

Personally, I think that the OCUP should have one exam but, rather go into the superstructure and metamodel in areas, look at the overall context of UML modelling. In my opinion, the content of the exam far exceeded the objectives.

Good luck on the SCEA - it's a great achievement and takes a lot of free time.

Hi. I'm planning to take the OCUP Fundamental exam shortly. Those of you who have passed already - can you tell me if the exam scope strictly adheres to the coverage map published on OMG's website (http://www.omg.org/uml-certification/UML_2-ToC-Fundamental.pdf).

Also, as part of the exam, are we expected to demonstrate our understanding of the OCL expressions/statements for constraints and operations provided in the UML 2 superstructure? What is the relevance of the Kernel diagrams to application modeling in general and the exam in specific?

Thanks for your help.

The coverage of the exam is very accurate to the content and it is highly recommended that you use the UML 2.0 Specification as a major source of your study. However, concentrate on the coverage areas and not any other areas. It is very important that you are very familiar with the specification. I had about eight years experience of UML but could still have failed due to the nature of the questions being specific to the specification rather than UML "real world" usage. This is a sore point with me because someone on this forum has passed the exam without any experience and therefore, in a commercial environment, how can this be justified to someone failing with say four or more years experience. It makes the exam a mockery and not a true reflection of an individuals capability. By learning the specification you will not be capabile of producing UML artefacts as part of an OOA&D methodology. The certification fails miserably and I am quite disheartened that the OMG have failed to recognise the true potential of a UML certification.

The Kernal diagrams are necessary to understand the specification but were not critical to the exam itself. Some of the questions are phrased from the specification and therefore it is beneficial to know certain parts of it word for word - which is impossible due to the shear size of the specification.

Good luck! If I was you I would simply concentrate on something else!

Ian, Thanks a ton - I agree with you 100% - there seems to be little correlation between the exam content and how UML is used in the real world - anyways, I think I'm still going to give it a shot, for whatever it is worth.

Best regards
