function wp_education_course_tab_customize( $tabs ){

	$tabs['custom_tab'] = array(
		'title'    => __( 'Custom Tab', 'wp-education' ),
		'priority' => 50,
		'callback' => 'wp_educationlearn_press_custom_tab_content'
	);

	return $tabs;
}

// Custom Tab content
if( !function_exists('wp_educationlearn_press_custom_tab_content') ){
	function wp_educationlearn_press_custom_tab_content(){
		?>
		<h3>Customm tab title</h3>
		<p>Lorem ipsome text here.</p>
		<?php
	}
}

I have try to add this on functions.php ( of the theme eduma) and no tab have been added on course page :-/

As beucherm, it was not working for me at first.

I'm using "eduma" theme and this theme also hook this filter with priority 9999 !

You have to change priority as follow to make it works :
add_filter( 'learn-press/course-tabs', 'wp_education_course_tab_customize', 10000 );
