I had no chance to get CET4/6 in school previously, but over many years till now, my work language is english and need to face lots of oversea customers with native english speaking in projects development, consider my career plan in the future, I think it's better to get a english certification and that will be benefit for my career promotion. so I checked and compared PETS and TOEIC, TOEIC will be more popular and competitive in foreign-investment company, now I am planing to collect some exam papers and do specific exercise to accommodate the exam. this is one of my little goals this year and hopefully I can pass it smoothly.
