There isn't really a direct translation. It depends on context. I would your sentence as "The test isn't so easy *that* you can pass it without studying." But in "Esto es como para no volver aquí nunca más," you can't translate it that way. That would be "After this, no one would come back," so the words don't have a direct translation into corresponding words. I hope that helps!

"Como para" in english is HOW TO. "El examen no es tan fácil como para aprobarlo sin estudiar". in english is "The test is not as easy as to pass it without studying." and your welcome.
