Andrew:
1. My favorite day of the week is Sunday because Sunday i'm not go to school.

2. My favorite day of the week is Friday because Friday next day is Saturday.

3. My favorite day of the week is Saturday because Saturday is Breaks day.

Correction:
1. My favorite day of the week is Sunday because, every Sunday I don't need to go to school.

2. My favorite day of the week is Friday because, next to Friday is Saturday.


3. My favorite day of the week is Saturday because, I can take rest all day long.


Explanation:
1. Fragmented sentences should be avoided. Always remember that you need a subject and a predicate to have a complete thought.
 
Example: Sunday I'm not go to school. (not a complete and organized idea)
             Every Sunday, I don't need to go to school.

2. Please take note of the proper usage of "comma." We use it for connecting a compound subjects or sentences.

Example: ...because Friday next day is Saturday.
             ... because, next to Friday is Saturday. (much better to read when we put comma)
