I suggest to don't miss the point, FOCUS ON LEARN, NOT IN PASS or reach the tec, if you're just pointing to the tec pass you're gonna miss a lot of advantages to have a gue instructor in front of you.
This is probably the strongest argument for taking Fundies early, in a single tank. At that point, you really are just there for the skills, as the card gains you nothing, really. You can focus on the instruction, ask questions, get input, and go off and practice. You can later transition in doubles, knowing what it is you have to accomplish in them, and come back and do the tech pass upgrade.
Taking Fundies in doubles with the NEED to get a tech pass to go on to the next class really does impact the value of the class for some people, I think.
