Just try to learn the important ones that you're going to need. In the other hand, you can also try to learn then focusing on the preposition, because exhausted preposition tends to have 3 or 4 different meanings. If you focus on the verb and then start adding prepositions, you're going to end nuts. It's also important to learn them in context, so instead of writing the meaning, just try to make some sentences that explain the meaning. You can use a free program, anki, to review them. And last but not least, if you have an ebook send me a private message, I'll send you a good book about phrasal verbs that I bought. Send me the PM in any case, because I'm going to try to convert it in PDF format. Have a nice day!
