On to the next letter!!
This one's easy because it already looks similar to the letter J, it just has a hat on top. So when pronounced it's a soft J sound, sometimes sounds like a ch (and you'll see it's symbol is similar to the Korean ch sound as well) but don't forced the ch sound when you see this letter, think soft, fast sounding J
You can also make this into the double consonant 'ㅉ' which has a HARD J sound, you spend more time making the J sound when you see this. (Make the double consonant by hitting the caps button on the Korean keyboard)
