Purchase an English-Korean dictionary and a Korean verbs book (see Resources), and take them to read wherever you go. Dictionaries come in convenient pocket sizes so they're easy to pull out of your bag and study while waiting in line at the supermarket or post office. If you truly wish to memorize Korean verbs, you must make a time commitment to review every day.
Make a chart of the most important verbs in your verbs book and practice daily. Invest in some index cards and write them down, making your own flash cards for easy review.
Purchase a Korean audio course and listen to it in your car or on the go. Most basic Korean courses include all the major verbs and are economically priced at under $40, and you are sure to hear the verbs pronounced properly when listening to native speakers. There are a few Korean audio courses available, most of which fall into two categories: courses that teach you how to speak Korean and courses that teach you how to speak and write Korean. Pimsleur's Basic Korean audio course teaches you how to specifically learn and pronounce Korean verbs without learning to write the verbs. Other language companies such as Berlitz and Barrons teach you to read and write Korean.
Peruse your local university course catalog to see if a course in the Korean language is offered. If not, you might be interested in private lessons from a native speaker. To find a tutor, place a phone call to the university's language department to find out whether there are any Korean students willing to tutor you on your Korean verbs. Also check out online marketplaces such as Craigslist.
