I will briefly tell you the situation: at school, teachers told me that mathematics is needed to count money, and I was sure that I was a hard humanist and was mainly engaged in Russian and literature.
But, as it usually happens, life took off in a completely different way. I
left the 9th grade with difficulty, having passed mathematics for 3, writing off and Russian for hard 5.
I entered a college programmer, at first I wanted to transfer, but at one moment I got acquainted with layout and found something interesting Then take
courses in front-end, fives in specialized specialties, but bribes in the subject of mathematics and math logic to get 3
Then the army, work as a junior, and now at Yandex data science courses. And then a firm realization came that I could take courses if I learned specific things needed for ds, mb I could even find a job as a ds jun (to use other people's tools, mathematics is not particularly needed).
But without fundamental things, I won’t go any higher.

And this is the essence of the question: how to learn mathematics in order to raise it to a very high level in an unlimited time period? Conditionally: I stopped in mathematics on quadratic equations, how can I raise it to the level of admission to the ShAD in 1-5 years?

Start with school textbooks algebra/geometry grades 6-11, which are now used in schools. You can also use different problem books and other materials for them.
Then you can switch to textbooks for technical universities. You can also use textbooks for technical schools. They are usually closer to life, less water, but the level is slightly lower. You can start with technical school textbooks, and continue the necessary topics in high school.
The school curriculum can be completely overcome by yourself. But further without a teacher it will be difficult. If there is a plug in some topic, you can find a tutor on this topic.

Hire a well-qualified tutor. He will be able to determine what the existing base is (what to build on), how much it is generally possible to achieve the desired level, and how much time it will take approximately. This is for starters.

And now a firm realization has come that I can take courses if I learn specific things necessary for ds, mb I can even find a job as a ds jun (to use other people's tools, mathematics is not particularly needed).

First of all, jumping into Data Science as a junior is only at the level of having learned to swim like a frog, immediately drive to perform on the Ironman at a distance of 3 km at speed. It’s worth going to DS when you have worked as a Python programmer for 3-4 years, that is, you have reached the level of a middle that does not float in the subject area, you will take out as a junior in DS if you have an information absorption level at the level of the Moscow Olympiad in mathematics (and then 40 percent of success ). So you won't finish DS, especially in solo, and you won't be hired as a junior.

How can I raise it to the level of admission to the ShAD in 1-5 years?

Why spend 5 years of your life on entering the ShAD, if you can start learning python right now and try to jump on the train of eternal self-learning as a junior. Where do you get such confidence that in 5 years Yandex will need you, I would give preference to 18-year-old smart young people who have potential, and they have not yet spent their time, because it is more profitable to invest.

I already answered this question here: Mathematics for machine learning and neural networks in the school knowledge base?
Specifically, about preparing for the exam, when the base is already there, Vitya spoke well on the Fless channel: https://www.youtube.com/playlist?list=PLiSyTNGp2j5...
In short, you need to spend about a year on school mathematics to lay foundation, and then take on the highest.
Matan, Linal and Terver at the basic level are studied more or less independently, the rest is already on top of them.

I heard that there are problems with personnel in Yandex, but I didn’t think that everything was so bad.

How to learn math

No way, mathematics is not a poem, it is unnecessary to learn it. All that you see around you is mathematics and you need to see it.

Conditionally: I stopped in mathematics on quadratic equations, how can I raise in 1-5 years

My lazy, goofy cub at 9 years old solved quadratic equations without any problems. No one taught him this, because at that age it is nafig unnecessary, but he just knew how to do it.
