I'm gunna teach you two letters today ohohohoo~~
So first we have the letter ㄱ which makes a SOFT 'g' sound. In fast or casual conversation, it can sound like a 'k' sound but generally when pronouncing yourself, you want to meet pronunciation between a 'g' and 'k' sound!
We can also make this into a double consonant by hitting the caps button on the Korean keyboard to make a~ ㄲ! This makes a HARD 'g' sound, as if you were pronouncing the 'g' in English! You spend more time pronouncing this letter when you see that it's doubled. -- this is the golden rule right here (always pronounce HARD when you see a doubled consonant)
BUT DO NOT MIX THIS LETTER UP WITH THE ㄴ! This letter makes the 'n' sound. There's no complicated forms of pronouncing this one, just a normal 'n' sound. You can also not make this into a double consonant. So maybe that can be a factor to help you decipher the two letters from each other.
PRACTICE PRACTICE PRACTICE OKAY!! If you're following my collection, I suggest writing down all of the letters and their sounds. Also wiring down each letter over and over again will improve penmanship and memorization!
