Fix Needed:

• The selected courses do not appear at the schedule right away.
• The remove button do not appear if you do not select the course at the same page.

• well-made feature and easy to use
• couldn't find any bugs

The course selection button on the explore page works as intended, however, I believe it should provide more feedback to the user.
Some suggestions are:

• change the background color of the button to green/red for selected/removed
• add "successfully added/removed" next to the button

I found one bug when reviewing the pull request. If you click on the select button for a course and then go to a different page (like the schedule page etc.) and then go back to that selected course it will not say remove, instead it says select again even though you have already selected it.

As chavab said before, once you leave the current page with the course you selected and then go back to that page to remove it, it will not say remove anymore. It requires you to click "select" and then remove instead of only needing to click remove since the course is already selected.

I agree with chavab and nancy, I checked it myself.
