- Use capital letters at the start of a sentence and for the word "I" (not just for most "I" words, but for all of them).
- Put a period at the end of a sentence.
- Don't use made-up punctuation like .. or .....
- Don't use smileys in a test. (<shrug> who knows?)
Yes, you obviously have problems with spelling, but you won't be able to fix that before next week. You can fix your punctuation. Your test will look better, and your marker will at least give you points for trying.
