Surely they could be improved...a few entries by one authorized person saving thousands of people confusion...a couple minutes of work saving collectively hours of work when you add up over the massive numbers of people taking this course.
I'd gladly chip in money to contribute to paying the people who do this, but there's no way for me to do this...I already am a paying subscriber.
The japanese course seems to be a work in progress. It constantly asks you about words it hasn't exposed you too before. This works when you can look at hints and hear the reading but for this course, either the hints are different from available answers or the reading is unavailable. An update is required.
When you have the letter "T" on its own you would pronounce it as "Tee" for the letter it is. If you put it with a "H" the sound changes to "TH" and it nolonger stands for that single letter.
That is kind of what is happening in Japanese. 前 is pronounced まえ but it can also be pronounced ぜん depending on the word it is being used in. (The different pronunciations are kunyomi and onyomi. There is also nanomi which is used for names).
It seems we need to memorize how words are pronounced (can't necessarily sound it out like in english) but you can reference dictionaries for pronunciation as you learn. I have been using flashcards, the jisho dictionary and youtube pronunciation/song videos to help memorize words.
がんばって! Keep at it!
