1.) Try to remember the last time you saw/used it and track back the places you've been in.

2.) If you don't want to join, that's fine, I'm sure the teacher will understand but if you do want to join, you should practice, practice, and keep practicing. It doesn't matter if you win or lose, having new experiences is great.

3.) I recommend avoiding chemicals that disrupt sleep, such as nicotine, caffeine, and alcohol. You could also try eating lighter dinners and avoiding screens 1 or 2 hours before your bedtime. You can try drinking plenty of fluids, especially water to cure dizziness quickly.

4.) I can't find my bag anywhere. I'm sure I must have left it in my room

5.) A lot of students didn't pass the english test yesterday. The test have to had been difficult.
