- ㄱ can be either a soft k, or a g if it's between two vowels. - ㅋ only has one sound, a stronger k than ㄱ ㅃ ㅉ ㄸ ㄲ ㅆ are really difficult to explain, is like holding your tongue for a second trying to say the letter, and then releasing it. But you need to hear it to actually understand it.

ㄱ is g like 학교 hag-gyo but you pronounce it like hakyo (if you found out the batchim ㄱ meet the same letter ㄱ so you should pronounce it like ㅋ ㅋ is k like 키스 kiseu you pronounce it kiseu ㅃ p ㅉz ㄸ t ㄲ k ㅆ ss I just try to answer your question, I know this is not perfect , but I hope a little bit helpful :)

ㄱ is pronounced as g, which means 가 is gha. ㅋ is pronounced as k, so 카 is ka. ㅃ= bb ㅉ=jj ㄸ= dd ㄲ= gg ㅆ= x (ss)
