Level 1 — Julia Foundations: First Contact with a Fast Language
Meet Julia and its story, install your toolkit and master the REPL, then build the essential vocabulary of the language: variables and core types, operators and expressions, control flow, and strings with basic input/output. Five learning modules (25 lessons, 250 fully explained questions) end with a 50-question Full Practice Test — everything you need to read and write your first real Julia programs.

Level 2 — Core Skills: Functions, Multiple Dispatch & Collections
Level 2 turns you from a script writer into a Julia programmer. Define and call functions in every style — long form, short form and anonymous — pass and return data flexibly with tuples, defaults, keywords and varargs, and unlock multiple dispatch, the idea at the very core of Julia. Then meet the everyday collections: vectors, dictionaries, sets and named tuples. Five learning modules (25 lessons, 250 fully explained questions) end with a 50-question Full Practice Test.

Level 3 — Data Structures & Classic Algorithms in Julia
Level 3 turns your toolbox into algorithmic thinking. Work with two-dimensional data: build matrices, index and slice them in two dimensions, reshape, combine and transpose them. Sort like a professional with sort and sort!, custom orders and sortperm. Search smarter with the find family and the classic binary search, run the timeless LIFO and FIFO algorithms with stacks and queues — balanced brackets, undo history, breadth-first frontiers — and put dictionaries and sets to work on frequency counting, two-sum, grouping and anagram problems. Five learning modules (25 lessons, 250 fully explained questions) end with a 50-question Full Practice Test.

The Function Forge: Mastering Reusable Code
Functions are where Julia starts to feel like a superpower. In Level 4 you will define and call functions, master every kind of parameter — defaults, keywords and variable-length lists — write anonymous functions and do blocks, wield the higher-order tools map, filter, reduce and broadcast, and take your first steps into scope rules and multiple dispatch. The level ends with a 50-question mock test that mirrors the real exam.

The Type Citadel: Mastering Types & Dispatch
Types are the skeleton of every Julia program — and multiple dispatch is the muscle that moves it. In Level 5 you will read the type tree with typeof, isa and supertype, convert and parse values safely, design your own structs, and meet Julia's superpower: methods that choose themselves based on the types of every argument. The level ends with a 50-question mock test that mirrors the real exam.

The Module Republic: Scoping, Pkg & Packages
Real Julia programs are republics of self-governing modules, not one endless script. In Level 6 you will declare modules and govern their namespaces, master using and import, tame global and local scope, split projects across files, and harness Pkg — adding packages, managing environments with Project.toml and Manifest.toml, and even shipping a package of your own. The level ends with a 50-question mock test that mirrors the real exam.

The Data Gateway: Files, Streams & Errors
A program that cannot read input or survive failure is a toy. In Level 7 you open the data gateway: reading and writing text files, the do block that closes handles for you, directories and portable paths with joinpath, structured formats like CSV and JSON, and the full error-handling toolkit — try, catch, throw, finally and the rogues gallery of common exceptions. You finish by building a robust, logging, self-validating file script, then prove it all in a 50-question mock test.

The Shape of Data: Parametric Types & Generics
One function for a thousand types, one struct that fits any payload — that is the Julia way. Level 8 reshapes how you model data: parametric structs like Point{T} and Pair{A,B}, the where clause that captures and constrains type parameters, Union{Nothing,T} and Union{Missing,T} for absent values, abstract types and the numeric hierarchy, the invariance rule that surprises everyone, and the anatomy of Vector, Dict, Tuple and Vararg. You finish by building a generic Stack{T}, then prove it all in a 50-question mock test.

The Speed Crucible: Performance & Parallelism
You cannot fix what you cannot measure. Level 9 turns up the heat: benchmark honestly with @time, @btime and the sampling profiler; read the compiler's mind with @code_warntype; then enforce the golden rule of type stability — hunting down global variables, abstract struct fields and the everyday traps that quietly slow hot loops. Broadcasting reveals that dot syntax is compiled, fused vectorization rather than a slow interpreter loop. Multithreading and Distributed put every core — and every machine — to work with @threads, @spawn, Channels and pmap. The closing module stacks the pro tricks: pre-allocation, @views, @inbounds, @simd, StaticArrays, functors and Val{T}, bound together by a repeatable benchmark-profile-fix-remeasure workflow and a 50-question mock test.

Code That Writes Code: Metaprogramming & Advanced Topics
Every macro you have ever typed — @time, @show, @threads — is Julia code writing Julia code. Level 10 opens the machine room: expressions become data with Expr, Symbols and quoting; interpolation and eval wire values into code trees; and macros are defined, expanded and kept honest with hygiene rules and esc. The built-in toolbox follows — @assert and @show, the logging family, @doc with the Test standard library, @__DIR__ and friends, the code generators @enum and @kwdef, and the compile-time switch @static. Reflection then puts the whole program on the table: types, fields, properties, methods, modules and the many ways to render a value. The closing module goes pro: custom string macros, generated functions and world age, a hand-rolled DSL, the Meta toolbox and the judgment to know when NOT to metaprogram — sealed with a 50-question mock test.
