I am learning how to associate a pinyin tone "shi4" with a character 是 and I am learning how to say the pinyin tone zhi3 or si4 are a couple of tough ones for me. I use memrise.com and there are lessons that help me drill and practice these two ways to learn pinyin.

yes, usually it's difficult for most foreigners, there is no ways better than practice day by day , Good luck
