Good saqlain bhai for not staying silent! Some people need to be reminded that their rude behavior won’t go unchecked. You stood your ground, and that’s exactly what they deserved. Keep speaking up when necessary respect has to be earned!
Yes, definitely yes! Middle class person can easily get adjusted in LUMS. And honestly telling, majority of the students in LUMS actually belong to middle class but some of them pretend to be from elite. Moreover, majority students of LUMS are cooperative and great people but there are some who mock and offend others. You will find such people everywhere so this should not be the reason to not apply to LUMS. You should surely apply to LUMS and there is no doubt that LUMS provides extraordinary opportunities to grow professionally and if you keep looking, you’ll be able to find nice and great friends in LUMS.
LUMS admission timeline is given on their website. Mein aap ko suggest karun ga k wo timeline apny pas note rakho aur follow karo. Hopefully wahan sy aap ko idea ho jae ga that how you should plan your application time-wise. But if there is still confusion, feel free to ask me again.
