Find the errors in the text and correct them:

This semester will be very important for me. If I organize my time well, I will finish my assignments. If I study a little every day, I will understand the subjects better and we will feel less stressed before exams. I also want to improve my English, so if I practice for at least thirty minutes daily, I will become more confident when I speak in class. If I have any questions, I will ask my teachers for help.

My weekends will also be important for my academic success. If I wake up early on Saturday, I will have more time to read and prepare my presentations. If my friends invite me out, I will go with them only if I finish my work first. I know that if I don’t rest, I will feel tired during the week, so I will try to sleep well. If I follow this plan, I will have a successful semester.
