Common Mistakes to Avoid
| Mistake | Correction |
|---|---|
| Spelling "space walk" as two words | It can be one word (spacewalk) or two words (space walk) |
| Writing "equipement" | Correct spelling: e-q-u-i-p-m-e-n-t |
| Saying "butter-fly" is not a compound word | It IS a compound word: butter + fly |
| Confusing short /a/ with short /e/ | /a/ as in "hat"; /e/ as in "hen" — listen carefully |
| Forgetting to include hobbies in self-introduction | Always mention what you like to do |
