After the practical examination of herbal medicine, it was rare for the first-year students to have an extra day free.

They will use the extra day to review astronomy.

Because in the astronomy course, the theoretical score only accounts for 20%, and the practical score accounts for 80%.

When Ralph and others learned about this ratio, they were all shocked and quickly went to the senior seniors to confirm.

However, it was in vain for Ralph and the others to ask, because this was their first time encountering the situation.

The seniors spread their hands in despair, and so did they, 80% practice and 20% theory.

They said this was not the case before.

In the past, astronomy classes only had simple theoretical exams, and there was no news at all about the practical exams.

In other words, now all students at Hogwarts, except for seventh grade, need to face a new type of astronomy exam.

As for the seventh grade, they have to take the Ultimate Wizarding Exam, which is extremely stressful, so the changes do not include them.

It is also to enable them to obtain good results in the Ultimate Wizarding Examination ().

Fortunately, Professor Sinistra gave the content of the practical exam in advance so that everyone could have time to practice.

That is to identify the stars.

If it weren't for the exam week and they couldn't go to the Forbidden Forest, the students would have wanted to ask their centaur friends for advice.

However, not all grades have time to review.

While Ralph and the others were having a break, some grades happened to have their turn for the practical exam in astronomy class.

Time flies by, and it’s time for the astronomy exam for first-year students.

The exam location was at the observatory, but the sky was full of dark clouds.

However, the freshmen have no doubts because the seniors have already told them how to take the exam.

Professor Sinistra will use magic to transform the stars on the observatory, and the students only need to follow the professor's prompts to find the corresponding stars.

It is worth mentioning that astrology is not static.

These horoscopes will change according to Professor Sinistra's will to adapt to more students.

The changing horoscopes are all real, and were recorded by the professor based on the passage of time based on Hogwarts.

Moreover, Professor Sinistra will not only ask about one star, nor will he only ask about the stars at the same time.

She may inquire about the position of the same star in the horoscope at different times;

It is also possible to inquire about the positions of different stars in the horoscope at the same time.

Of course, in addition to individual stars, there are also questions about constellations.

Generally, questions are asked about the constellations first, and then about the individual stars.

If you answer well, Professor Sinistra will tell you about the extra points and ask you if you want to join.

Moreover, if you meet a student with really good theoretical knowledge, the professor will even invite you to take an exam with extra points, and your score will also be 5 points.

But the seniors told them not to agree to the invitation.

The real astronomical phenomena are completely different from those simulated by the professor, and the weather cannot be perfect. There are always some regrets.

However, when Ralph and the others found out, it was already too late and they had already agreed.

It should be said that most of the Ravenclaw students participated.

….

The next night, those students who were eligible to take the extra-credit exam and agreed to it were called to the Room of Requirement.

Looking at a familiar scene, a door suddenly appeared on the wall. Open the door and enter.

Ralph and the others knew this was the Room of Requirement.

In order to better study the stars and eliminate the influence of weather on observations, this room came into being.

Professor Sinistra calls it the "astrology hall".

Based on her needs, the Room of Requirement simulated the upper limit of what it could achieve.

Then, professors came to help and improved on the basis of the Room of Requirement, and finally achieved the current success.

fruit.

The astrology hall is circular in shape, with walls about 1.3 meters high. The ceiling is a hemisphere, covering the room.

It has two states, one is the non-observation state; the other is the observation state.

In the first state, the walls and ceiling of the astrology hall are visible.

The room was filled with dim and soft light, the source of which was unknown, and only the outline of things could be seen.

For some places that needed lighting, the professors prepared a magic candle or a magic flame in a transparent cup.

But their light will only be limited to a spherical range of a certain radius.

On the hemispherical ceiling, there are stars evolved by magic flowing.

This horoscope is the horoscope at the moment before that time, including during the day.

At the beginning, in order to come up with this function, the professors spent a lot of time and energy, including Dumbledore.

Dumbledore did a lot of things that other professors really couldn't do.

We all know that the light of each star in the sky is different, and the magical meaning contained in it is also different.

Based on this, the professors analyzed the starlight of all the stars that have been observed so far, encoded it and recorded it.

And mark some stars used for positioning in the blank star chart in the astrology hall system.

After the general constellations and some familiar positioning stars are marked in the star map, the system will collect the starlight on its own and mark them in the corresponding positions on the star map based on the difference between the starlights.

Professor Sinister also uploaded the star map he compiled to the system for comparison.

If a star is in the wrong position, the corresponding star in the star chart circulating on the ceiling will emit a persistent red light.

Its position in the professor's astrology chart and the position on the system chart are empty, and a red light will flash there.

A red dotted line will also appear between the two.

At this time, the professors need to judge whether there is a problem with the system or with her star map.

Secondly, if strange starlight is detected, the system will also record it in its own star map and continue to emit green light.

The second state is observation mode.

This mode will not be open to any young wizards because it is very dangerous.

In this mode, walls and ceilings become transparent.

At the same time, hidden astronomical telescopes will appear on the tops of some towers in Hogwarts Castle.

Originally, these telescopes evolved on their own from the Room of Requirement.

But in order to reduce the consumption of magic power and the malicious gaze from outside, the professors replaced them.

….

Dumbledore specifically asked them to record the data from these telescopes, and then he took the data to find an old friend.

Soon, he brought back several astronomical telescopes that exuded a luxurious atmosphere.

Give it to the Room of Requirement and help the Room of Requirement assimilate it into a part of yourself.

The Room of Requirement placed it where the simulated telescope had been.

At the same time, Dumbledore also brought a large number of glasses.

Both the telescope and the glasses were specially made by Dumbledore after he got rid of Nico Flamel.

They can reduce the magic power of the wizard when observing, so as to avoid magical interaction with certain things and attract attention.

Later, Flamel couldn't let go. He was afraid that something would happen to Hogwarts and lead to the destruction of the entire magical world, so he came to Hogwarts.

However, these are all secret things, and no one except the professors at Hogwarts knows about them.

Now that they are all here, Mr. and Mrs. Lemay have no intention of leaving right away.

After casting magic on themselves, the professors gathered around the Flamel couple and started walking around Hogwarts.

Sensing the changes in Professor McGonagall and Professor Sprout, the Flamel couple also sent their blessings and some small gifts.

Professor McGonagall and Professor Sprout thanked them and accepted the gift.

"It is a gift given by the elders and cannot be turned away."

Compared with the Flamel couple, they are still juniors.

Walking on the lawn and looking at the cheerful and energetic students, LeMay and his wife looked at each other and smiled happily, as if they were reminded of their youth.

Decaying souls and old bodies, if it weren't for the hustle and bustle of the world and the responsibilities they bear, they would have chosen to leave long ago.

However, they have also begun to prepare for death, but the preparation time is a little long.
