Very good! A native English speaker would easily understand this. All mistakes were very minor. 1. “Presential” is a correct word but is not very commonly used. In American English, at least, we usually use “in-person” when contrasting with online classes, video calls, et cetera. 2. I inserted “also for” in between “but” and “knowing”. When following the words “not only…” earlier in the sentence, the usual follow-up is “but also.” Additionally, you typically repeat the preposition when a conjunction comes between its first object and a second object, hence “for”. 3. I deleted the “about” in between “knowing” and “how to”. It’s not necessarily wrong, but this change makes it seem more natural. I also think it helps get your idea across better – younger kids need to actually learn how to use these skills, not just know about using these skills in a theoretical sense. 4. I inserted “interact in” between “and” and “the environment” because the phrase “how to” needs a verb to follow it for each phrase. Think of it by splitting the sentence after “but” in two – “but knowing how to socialize” and “and knowing how to [interact in] the environment.” That second half needs something like “interact in” to sound right/be correct. This is a common error that even college graduates make, and it’s only really relevant to more formal writing, so don’t worry too much. 5. I moved “are needed” to the end of the last sentence. It’s not incorrect, but it does sound really awkward and even archaic (maybe used this way in the past but no longer used this way). 6. Lastly, I split a few sentences in two. These are what we call run-on sentences” in English, because they’re too long (the rules for what counts as too long are complicated, even for native speakers). This is really only relevant to more formal writing – in everyday speech and non-formal writing, this really isn’t an issue. Native speakers make this error all the time, so it’s not something to worry about too much.
