Hello, Kimi. First of all, Chris has given good advice, so I don't know why he has gotten down-voted (or why your question has gotten down-voted). I’ve read your question and am happy to say that in addition to my hundreds of hours’ experience teaching TOEFL, I’ve also successfully prepared teenagers for IELTS, the ACT, and the SAT. Feel free to visit my teaching profile or message me with any questions that you may have. You’ll notice my rates are higher than those of the average teacher on this site, so my services would be most appropriate for the consumer who understands that it's not about how many hours you spend in class, but how much you advance your language skills — while having fun. If you’re not enjoying yourself, you’re not learning.
If you take a look at my profile, the first thing you’ll observe is that I actually have experience learning languages, so I’m constantly refining my methods and choosing the most appropriate ones for each student.
I’m always happy to answer any questions you might have, so feel free to write me whenever you would like. Have a wonderful day :)
Sincerely,
Phil
