Orochimaru was happy because he has upgraded his spin to grade E. Morever, all his stats has passed the threshold and reached genin.
Now his stats are
[Name: Orochimaru
Strength: 560
Agility (includes,speed,reflexibility and reaction speed): 620
Endurance: 580
Spirit or wisdom :1000
Chakra:780]
[Ninjutsu:
The spin (upgradable)(current rank f) - Spin a body or an object at speed at 500 rpm.
(Current progress:100 %)
------------------------------------------>
The spin(upgradable)(current rank E)-Spin a body or an object at speed 700 rpm.
(current progress:0%)
After breaking the limit he felt as if his chakra tenketsus have been purified by his dense chakra which certainly became light purple in color. And he suddenly felt that he was able to advance in wether Genjutsu, ninjutsu and taijutsu at speed higher than usual.
After that he came to know why in civilians book it was written that a person is blessed by world if he became genin before age of 8.
Although he was certainly able to do practice more but it's nothing like said to civilians maybe this idea is instilled in their heart that Ninja's are also blessed by world.
In reality as chakra passed a threshold it became powerful enough to purify tenketsus and chakra pathway which leads to rapid increase in strength and practice speed increased.
But if the chakra do not pass threshold of genin before 8 his tenketsus impurities are not able to be purified because they have taken root in teketsus and are not purified by that amount of chakra.
But civilians think as rapid increase due to enlightment of world and as for why for one month, because they get used to that practice speed that it looks that it's normal speed instead of rapid increase.
Well it certainly a way to make civilians believe that ninja is great that even world is giving it's blessing.
Although this world has higher power level than anime means 5 year genin is really a big feat. But it's not like he will tell anyone about it.

After some time orochimaru can say that he was familiar with everyone after being in one class for long period of time. Although he can't say that he is close friend, but he is familiar enough to say more than 2 words.
After all it is invetable to be familiar with everyone after being with a class of 15 students.
Everyone has applied for early graduation.
Although nobody has passed threshold of academy students in class but various things like taijutsu , Genjutsu and ninjutsu can be piled to make them qualified enough to be genin.
Morever their training speed is faster than most people after purification of chakra pathways, after all they are geniuses. So, they are quite powerful if you ignore the physical qualities.
Today was the day of examination for graduation to genin. And the exam includes written test, and combat test.
After arriving at exam venue he saw that many students were there, most of them were of 6 class and some early graduation student. Maybe his classmates venue is different from his as he didn't see them.
After entering the class he took his seat. Although because of small age and body he stood out but nobody came to bully him like classic cliche situation.
After all to become ninja you must never underestimate anyone. Morever he was allowed to take exam at such age means that he is talented person.
At appointed time examiner distributed us sheet for written exam. After seeing the sheet orochimaru wrote answers in 5 minutes and didn't even checked it second time.
With the amount of knowledge he has learned if he wasn't even able to get full marks in exam then his name will not be orochimaru.
After that he just meditated. During this period of time it became his habit to meditate whenever he has time. Maybe it is because it helps him calm his mind,or maybe it let him feel chakra more profoundly or another reason but it has just become part of daily life.
After exam they were tested on basics tought in acedmy like shuriken throwing, basic 3 ninjutsu , etc. Orochimaru passed all these exams with full marks, which not a big feat after all it can be done my most of people.
Lastly was match with students to test their combat abilities. There were various spaces for many matches.
Orochimaru was called on one of that
He was little suprised to see his opponent . His opponent was of about age 7-8 year old plus her white eyes explained her origin from hyuuga clan. But that's not what suprised him, it was because she resemble main heroine of Naruto anime Hinata hyuuga.
But he still remained calm, so what if she look like her, nothing to do with him. He made seal of confrontation and opponent did same in response.
Hyuga took gentle fist stance
But not seeing any stance, hyuuga chan kept cold expression like always, but you can see that the coldness increase several times. But she is taught by elders since childhood, and regained calm. After all ninja should be always be beware of opponent trickery.
Seeing this the refree started match
"Hajime"
As soon as the match started hyuuga moved in a flowing motion and coated her fingers in chakra. Seeing her attack orochimaru shifted sideways leisurely to avoid the strike as if it was not fast.
But it was not the end as she kept attacking in continous manner , although they all missed as orochimaru dogdged them by hair length, it was not that he can't dodge earlier but it's a way to not do excess movement than necessary.
With his grasp of terrain and opponent he remove excess movement in body.
Even tough he can end this match already but he didn't do this. Of course it's not because she was beautiful girl or resemble main character. Even if a beautiful woman or anime character is his enemy,, he will kill without mercy.
The main reason was he was very interested in gentle fist fighting style or more importantly the hyuugas as they are capable to blocking chakra flow in tenketsus.
