😴 B1 Exam — The Science Behind Sleep
A comprehensive B1-level exam with 30 multiple-choice questions themed around the science behind sleep. Grammar topics include: reported speech (said/told + tense shifts), second and mixed conditionals, present perfect continuous with since/for, passive voice (is believed, is released), gerunds as subjects (using screens affects...), relative clauses (which), verb patterns (advise to, suggest + -ing), superlatives, hardly, despite + -ing, and make + object + adjective. Vocabulary covers: sleep science (melatonin, REM sleep, stages, brain activity), health effects (concentration, mood, memory, exhausted), daily habits (fall asleep, wake up, bedtime routine, caffeine), and academic language (research, effect, process, produce). All sentences use realistic teen situations: school stress, screen time, exam pressure, and sleep schedules. Features: sidebar navigation, flag for review, progress tracking, localStorage persistence, instant scoring with explanations, and results breakdown.
