no mtn dew ? <| sep |> Hi ! 1 Oh I see . Thank you ! 2 I ' ve been away from high school subjects for 3 years now . So I forgot most of math or physics or chemistry we ever learned back then . I ' d have to revise my high school lessons first before being able to do practice problems . I tried to do some nonetheless though , and I am doing Khanacademy ' s math lessons atm , but it ' s still stressful as I have to do it in secret from my parents . So whenever I hear they are coming into my room or passing in front of my room which is often , I ' d have to hide my writing and put the phone away and pretend I was revising my med school lessons in case I was studying at the time or doing something else on PC in case that was during my break . So it is getting really stressful and inefficient as I don ' t get the chance to focus for a very long time . 3 This is really a great idea . Thank you so much again !
