Stuart, your code looks perfect to me. It passed when I pasted your code (I copied)-- try it again, it might be something messed up in the browser state/cache.

from django.contrib import admin

from . import models

class TextInline(admin.StackedInline):
    model = models.Text

class QuizInline(admin.StackedInline):
    model = models.Quiz

class AnswerInline(admin.StackedInline):
    model = models.Answer

class TopicListFilter(admin.SimpleListFilter):

    title = 'topic'
    parameter_name = 'topic'

    def lookups(self, request, model_admin):
        return (
                ('Python', 'Python'),
                ('Ruby', 'Ruby'),
                ('Java', 'Java')
                )

    def queryset(self, request, queryset):
        if self.value():
            return queryset.filter(title__contains=self.value())


class CourseAdmin(admin.ModelAdmin):
    inlines = [TextInline, QuizInline]

    list_filter = ['created_at', 'is_live', TopicListFilter]

admin.site.register(models.Course, CourseAdmin)
