What is a system whereby students are grouped together by ability so they can be taught with each other?

Ability grouping especially in the UK is practice founded upon the idea that students need to be taught accordingly since they have fixed levels of ability. Basically, it groups children according to the talents in class. Some may agree that Ability grouping is an effective way to handle differences in students' abilities while will some strongly disagree. Those who agree say it increases students' achievements by allowing instructors to adjust to the pace of students’ needs while those who disagree say it is an unfair procedure.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
