When you are practicing these homework, please do not go straight to the answer key and try your best first. Do not lower yourself by cheating. Getting the instant answer might make your work easier but it is clearly not good for yourself. Not only will not make you improve but also make you a dishonest person. It is always fine if you get the answer wrong as it is normal and you can use it to push yourself more.
