Well owing to the number of words that u might be needing, it is best to have a periodic schedule. Say 10 words in the morning, 10 in the afternoon and 10 at night. It might be tough to follow this routine initially, but with practice, you can. You can repeat those words which you learn on alternate days. Finally, on week ends you can repeat the words which you study throughout the week.
This will help you to form memory maps and with periodic revision, you can master the words.
