Hi leslie Judging from your examples, you seem to have a good understanding of adjectives. When you get confused just ask yourself if the word would discribe a noun or a pronoun. If the answer is yes, it means it's correct.

Hello Leslie! How are you? If you’re interested in learning English I can help. I have a range of courses to offer, conversational, grammar, pronunciation, even Australian English if you’re interested. Have a look at my profile and profile video and book a trial lesson if you wish. I have 2 years of experience teaching so I can help with any problem you may have. Have a great day
