Understanding is a process of comprehension and is actually termed as the limit to conceptualization. To understand something means to have conceptualised it up to a given measure. Understanding anything requires focus, concentration and attention. The process of understanding is also called intellection and is a psychological process.
Understanding is always handy to learn more effectively and quickly. Crammers don’t benefit in the long run. They know about things only for some limited period. Understanding makes things clear to you so that the k knowledge stays with u for a lifetime. So, focus on clear understanding or intellection. According to Friedrich Nietzsche, “To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one's experiences in common.”
