* Your bed: The comfort and relaxation associated with your bed make it very easy to fall asleep or get distracted by other things.
* A crowded, noisy cafe or public space: While some people find ambient noise helpful, excessive noise and the constant visual stimulation of other people can be overwhelming and prevent concentration.
* In front of a TV or computer (unless actively using educational software): The constant stream of visual and auditory information from screens is highly distracting, even if you think you can multitask.
* A place with strong emotional associations: If a space is linked to stressful memories or strong emotions (like an argumentative family member's house), it can interfere with your ability to focus.
* Anywhere with unpredictable interruptions: A place where you're likely to be constantly interrupted by others (e.g., a busy dorm common room) will make it hard to maintain concentration and make progress.
Ultimately, the worst place to study is anywhere that hinders your ability to concentrate and retain information effectively. The best study environment is one that is quiet, comfortable (but not *too* comfortable!), well-lit, and free from distractions.
