The reason for the testing is because adult Jews are responsible for carrying on the traditions to the next generations. So in order to be sure it's done so correctly, they train you & test you.
I guess if you want the responsibility, then you should train hard for it, for such training should also continue on throughout the rest of your life.
I will admit I haven't heard of many Spanish Jews. Here's a question though: have you thought about checking into Messianic Judaism? These are Jews as were the Apostles of Jesus Christ...they're Jews, they follow the traditions handed down to them, continue with all the ordinances and such, but have accepted Jesus as the Messiah. That, in my opinion, is also the purest form of Judaism. Just a thought.
