Where to start learning?

Question

Mathematics

Good day. I study in one of the technical universities with a degree in information security. 2 course. At one time, due to his own slovenliness, he missed the development of the foundation of knowledge (mathematics, etc.). In the future, I want to become a good specialist in my field, and in the end I would like to be engaged in information security management. In this regard, the question is how to start studying now to achieve what you want, and how to close problems in knowledge in a more or less quick time frame.

Answer 1

start with the knowledge you missed and monitor the current situation, work as an intern, etc.

information security management
