= Bolt Tutorial, part II: Exercises =

Now let's add an exercise.
Create a file "exercise1.php":
{{{
<?php
echo "Conifers are so named because:";
bolt_exclusive_choice(
    array(
        'They carry their seeds in cones',
        'They are cone-shaped',
        'They originated in the Coniceous era',
    )
);
?>
}}}

and edit course_doc.php:
{{{
<?php
return sequence(
    name('course'),
    lesson(
        name('lesson 1'),
        filename('lesson1.php')
    ),
    lesson(
        name('lesson 2'),
        filename('lesson2.html')
    ),
    exercise(
        name('exercise 1');
        filename('exercise1.php');
    )
);
?>
}}}

Start the course from the beginning.
When you get to the exercise you'll see

You'll then see either

[[Image(bolt_right.jpg, nolink)]]

or

[[Image(bolt_wrong.jpg, nolink)]]

depending on whether you answered the question correctly.

== Review and repeat ==

Suppose the student doesn't perform the exercise correctly,
and you want to let them (or require them to) review the lessons and repeat the exercise?
