Alt vs. non-alt? If you listen to the Sentences from the Top X Words and decide to skip the Sentences from the Top 1000 Words - Review Part Z, there will be additional new words in the Sentences from the Top 1100 thru 1600 Words. If that is the case, you will want to use the Alt practice sets.
This New Word Drill practice set contains all of the new words introduced in the Sentences from the Top 1100 Words. Learning new words one at a time may be more efficient than learning them within sentences.
For each word, try to head-copy it. First, the word is sent in Morse code. Then it is spoken. And finally, it is sent again in More code. If you missed it the first time when it was sent, the second time allows you an opportunity to learn the words.
