To find out how many classes you need to complete each day, you can divide the total number of classes by the number of days you have:
\[ \text{Classes per day} = \frac{\text{Total Classes}}{\text{Total Days}} = \frac{233}{45} \approx 5.18 \]
Since you can't attend a fraction of a class, you would need to round up. Therefore, you should plan to complete approximately 6 classes per day to finish in 45 days. This would give you a total of 270 classes over 45 days, allowing for some extra time.
If you want to stick strictly to the 233 classes, you would need to complete 5 classes most days and do 6 classes on some days to meet your goal.
