Hello everyone,

I’m currently specialized in HR, and the time has come for me to try new things that suit me better. For this, I am aiming for a data science bootcamp, which requires a minimum level in mathematics to integrate the training.

Here is what is stated on the site:

“In order to join our Data Science course, you also need a minimum level in Mathematics and to be familiar with concepts covered in high school’s scientific section. We need you to be comfortable with **functions, their derivatives & systems of linear equations**”.

The context is as follows: the technical selection interview should take place around December, and I haven’t touched a math textbook for about 15 years, knowing that it has never really been a favorite subject for me (except now, otherwise I wouldn’t be bothering you with my problems).

So, I’m wondering what I should work on to be, as they say, confortable with:

- Functions
- Their derivatives
- Systems of linear equations

Thanks in advance for your help!
