How do I learn the ninety-nine names of Allah?

Learning the Qur'an requires dedication and determination. Quran is usually memorized by reading loudly but not very loudly. Just pick the first few names and recite them loudly, to the extent where you can hear yourself speak. After reciting the names a few times, try to recite them on your own without looking. If you can do it, recite the names a few more times without looking. If you can't then consult the book and repeat. If you learn the first few names then move on to the next few. Learn the names slowly and in batches so that it is easy to learn.
