FSOSD: Guided Financial Services Open Source Study Practice
Independent original practice for the FINOS Financial Services Certified Open Source Developer (FSOSD) certification.
$79 practice exams are gatekeeping. Mine are $9 because it should be. Written by someone who works in cloud and AI at Microsoft NZ — for people like us.
I just passed with a 777 (Yes, Seriously). This video helped me tremendously.

How does purchasing work?
Click "Unlock $9" above → pay securely via Stripe → all 250 questions unlock straight away in that browser. Your licence key is shown on screen and emailed to you from noreply@aguidetocloud.com — you only need to enter it on another device or browser. No account needed. Each cert is purchased separately at $9 for 1 year of access.
Can I use my purchase on multiple devices?
Yes. Your licence key (e.g. GD-XXXX-XXXX-XXXX) works on up to 3 devices — phone, tablet, laptop, desktop. On each new device, go to the practice page and enter your key.
Do I have to enter my licence key every time I visit?
No. You enter your key once per browser and it's remembered on that device until your 1-year access expires — so on your usual device you just open the page and start. You'd only re-enter it if you clear your browser data or switch browsers. Tip: avoid private/incognito windows, since they forget the key when they close.
