This has not been effective for me. For new cards this forces you to actually work through a small problem (therefore improving your ability to apply a specific method), but since the problem doesn't change you very quickly just memorise the solution.

On further reflection I found that those cards just were an attempt at avoiding actually practicing something, but this isn't really possible. If you want to be good at solving integrals, than you do actually have to solve lots of integrals. Anki will not make you proficient at this if you don't also put in the time to frequently solve integrals. Instead what it can do for your is keep the various techniques for integral solving close to the surface, so that you can relearn them much quicker if you haven't solved any integrals in months. You skip the step of having to rediscover all the techniques.
