Manh Tung - Student at Hanoi University of Mining and Geology

eJOY - the "savior" that helped me overcome my fear of learning English vocabulary.

  • I used to be extremely afraid of learning English vocabulary because I would forget everything I learned, which completely killed my motivation. Everything changed when I discovered eJOY. With eJOY, it’s not just about looking up and saving words; I can also review vocabulary using the spaced repetition algorithm, which helps me effectively remember the words I’ve learned. From the early days with just 100 words saved in my word book, my eJOY word bank has now grown to over 3,000 words! What I love most about eJOY are the incredibly diverse and fun vocabulary review games, which make revising vocabulary easier than ever. I’m truly amazed that now I can read newspapers, watch videos, and even read specialized documents in English with ease. Thank you, eJOY, for being my companion on this wonderful language-learning journey!
