What mathematics will be sufficient for further study of higher mathematics?

Question

Mathematics

I have been marinating at khan academy for a long time, and I had a question after I pass all the mathematics courses at khan academy, will it be enough for me to start studying higher algebra, math analysis, discrete mathematics, pain algebra and also graph theory? Looking through school textbooks. I was horrified by what tasks there are, and how much I have to learn and still solve the most real complex examples. In general, looking at the school curriculum, in this case, I will raise my mathematics for not about a year, but for three years. I don't want to spend a lot of time and ask the opinion of you pros who know math. Will the level of khan academy be enough for further development of a university level or not?

Answer 1

Look at my Algebra (according to Kiselev's textbook). www.nerepetitor.ru/algebra.html
+ in the same place on the main page you choose a topic from mathematical analysis, and you will see what you need to study minimally, "from the stove".

Answer 2

Start pain algebra immediately!

Answer 3

I video is a great channel where you can develop math with very accessible explanations. The guy uploads a new video every 2-3 days, they are short, worth a look ...
