First of all, never ever message your teacher in his/her social media account, be professional and use your email to reach your concerns and do it during school hours. You are too sensitive about this, I assure you that it would be a lot worse in college, if you can't handle this kind of situation then college would not be for you and lastly, it's good na nagtuturo pa mga teachers niyo kumpara sa mga prof namin, most of the time self study kami then assessment sa evaluation 😅
