Did you ever Take a Certification Exam for Something?

I have a certificate that tells me I speak advanced English (yes it actually says that in the certificate). My study consisted in me talking with other boring people like me. And play video games with my homies. The easiest exam I ever had :D

I did the GMAT during a graduation internship, so I couldn't really study for it. I passed it - I needed a score of 600 for my Master study, and got 620 - but that was more luck than anything (though, I was part of the 91st percentile of English, without studying at all, so that was quite nice).

I also passed the TOEFL, also necessary for my Master study, but I didn't bother studying for that as my English is easily fine enough anyway.

too many to list. some were easy, some were difficult. Some I took cold, some I studied for months.

Seems like too many. For some, I've "studied" for years. Haven't failed yet.

I got my private pilot license, then IFR certification. Yes I studied, about 8 months for PPL, then another 4 months for IFR.

Most "certifications" I've taken were a crash course, like two weekends or two weeks or two months. Usually I just read the materials they hand out maybe twice if there's a lot of info, and so far I've passed them. Some were much easier than others, the practicals were not as easy to "study" for sometimes.

I won't be able to remember 'em all. but the hardest certificate that I have gotten is for learning Japanese language(N4), it's not even halfway to fluency but it took me about 2 years. had to stop leveling, got busy.

I have IT PM and Service Management Certs. My studies ranged from 2 weeks to 2 months. I, thankfully, passed all of them.

Depends what you mean, there's a lot I got just for being 'present' (with an excuse for a test afterwards), so I wouldn't really count them, and there were some where you had to use your brain and actually listen to what the guys in front of you were rambling about. In the end, most of 'em are just another piece of paper nobody really cares about.

I got 7 Microsoft certificates to MCSE, but you can just find the answers online and cram (still i failed 2 times or so).
Done another 8 computer related, might have also failed once or twice. Both i studied some weeks into it.

Tried university level at one point but that was just a debacle.

Just some programming ones. Did my usual method of fake tests for a few days beforehand and had no trouble

I got a Goethe B1 certificate (German language) when I was in secondary school/high school/whatever it is called.
It was just the first year our school organised extra ("higher level") classes for German. For French & English (Cambridge advanced) it already existed a couple of years longer, but I didn't take French anymore and for Cambridge you had to have high grades in English (something I lacked for almost all courses) in order to be able to apply for it.
I was bored in regular German class, which was btw also at B1 level according to the books, as most things were easy (vocabulary, speaking, reading & later on grammar as well) so I thought this would be a nice challenge to take on.

For the certificate, we practiced every week during the 2 or 3 free hours that all 9 of us + teachers had together. The exam turned out easier than most tests we take at school so everybody nailed it and some were even recommended to take the higher level exam as well.

From that exam until now (about 5 yrs) I may have spoken maybe 2 or 3 full sentences in German and I think I forgot most stuff, but hey, it's still a nice addition on my resumé xD

English. Yes.
Regional language. No.

haha

Did the M’Naghten test. Easiest certification I ever had.

Took the IELTS test - didn't really study 'cause I'm quite fluent in English so I didn't feel the need to
Taking a Goethe B1 in February/March and I've attended the prep course for it... and still I'm a little scared I won't pass XD

QTS, ODP and Degree. All took like 4 years.
