Quantitative Finance From Scratch

If you work through it seriously, yes for the core of the field: it starts with returns and probability and builds step by step through statistics, pricing, portfolios and advanced models in four levels, each step derived and coded. Some advanced modules are still coming, and it is a very solid foundation to break into quantitative finance.

Yes, a lot. Every module comes with Python code to run on your own computer, exercises with fully worked solutions and a mini project, one small program you write yourself. On top come the larger CV projects, complete tools with full code (Foundations includes one, Pro all of them), and the interview prep has its own Python coding category.

Yes, much longer, usually 25+ pages. An e-book chapter fits on one page, and the module covers the same topic in full depth with the math, code and worked exercises.

You choose Foundations or Pro on the pricing page and pay once. When you buy, you create a free account with your e-mail address, and your plan opens as soon as you sign in, on up to two devices. Paddle handles the payment and the invoice.

Yes, you pay once: no monthly membership and no thousand-dollar price tag, one clean payment at a fair price. Pro also includes the new modules as they are released.

It teaches the methods that quant, risk and asset management roles use, with code you write yourself and projects you can show. How much it helps depends on your own work and on the job market.
