Are you sure you're not reinventing established theories and algorithms? Those problems are supposed to be hard because they're based on ideas discovered by the most brilliant minds. If you can do them in 2-5 hours with no background you might actually be real good.
Depending on what level of familiarity you have with the material, you might be selling yourself really short. Deliberate thinkers (often misunderstood even by themselves as "slow") are often the most reliable because they take the time to understand and think things through.
Please take a deep breath and start with a reasonable supposition. If "easy" problems are taking too long for you, maybe there's an easy way to "solve" it (memorizing the patterns and knowing the most likely to be tested algorithms).
Like others say in this thread, not only are those problems unrealistic, it's much like test prep for standardized tests that you may have taken getting into college.
