Programming Typing Practice

Practice copying code with brackets, operators, capitalization, indentation, and line breaks. Start with symbol and naming drills, then choose Python, JavaScript, SQL, HTML/CSS, Java, or C/C++ with C snippets. These exercises measure typing accuracy and WPM; they do not assess programming ability.

0 of 8 complete

  1. 1

    Symbols Intensive

    Not started

    The punctuation that shows up in nearly every language: braces, brackets, parens, comparison and logical operators, and arrows.

  2. 2

    camelCase & snake_case

    Not started

    The two dominant variable-naming conventions, practiced back to back so your fingers get comfortable with both capitalization and underscore styles.

  3. 3

    Python

    Not started

    A real Python snippet, indentation preserved exactly, using the Code Typing surface.

  4. 4

    JavaScript

    Not started

    A real JavaScript snippet, indentation preserved exactly, using the Code Typing surface.

  5. 5

    SQL

    Not started

    A real SQL query, with the keyword-heavy, punctuation-light style typical of database work.

  6. 6

    HTML & CSS

    Not started

    A real markup and stylesheet snippet, practicing the angle brackets and colon-property syntax of front-end code.

  7. 7

    Java

    Not started

    A real Java snippet, practicing the verbose, brace-heavy style typical of statically typed object-oriented code.

  8. 8

    C/C++

    Not started

    A real C snippet, practicing pointers, includes, and the terse syntax common to systems programming.

How to use these lessons

Start with Symbols Intensive if brackets and operators interrupt your rhythm. Follow it with the naming exercise to alternate between capitals and underscores. Then choose a language lesson you recognize, so you can focus on entering the characters rather than interpreting unfamiliar syntax.

Type indentation and closing characters exactly as shown. These drills do not run the code or provide editor autocomplete, so they measure transcription rather than programming ability. For varied snippets after the course, use the code typing tool.

Start with a careful attempt, then repeat the lesson with attention to one difficult transition. Compare results within the same lesson rather than across unrelated passages. Completion and best scores stay in this browser when local storage is available. These exercises are practice, not professional certification.

Continue with varied code snippets

Use the code typing tool to switch languages and try another snippet. Follow the code typing practice routine to choose a focused drill and compare accuracy.

For indentation, type spaces exactly as shown and press Enter for each line break. Tab moves focus. These exercises do not supply editor autocomplete.
