There are three days of experiments and an exam on the fourth day, so I will take two days off.

As the title.

There are three consecutive days of laboratory classes from 8 am to 8 pm. On the fourth day after the three days of experiments, there is another half-day experiment in the morning, and there is also a final exam in the afternoon of the same day.

Therefore, these four days will be quite busy and I won't have much time to write. I may not be able to write every day, so I'll take two days off.

If I am extremely busy on all four days and cannot squeeze out any time, I may have to give up full attendance next month and take two more days off.
