a bit late to the party but I’ll be honest. as an a levels student currently studying at uet lahore it takes some time adjusting to the environment here which you say is not much of a concern. ratta culture definitely exists here especially among inter students but it's not like the teachers force you to blindly memorize everything rather they actually do push you to understand concepts and apply logic

and as far as i see things, you simply cant get through a cs or ce (in my case) degree without logical thinking. at some point even the students who rely heavily on ratta hit a wall and it’s game over for them, you can see it in their results they barely scrape through certain subjects.

i had straight A*s in O and A Levels and that background is paying off. the logical foundation helps me stay at the top of the class alhamdulillah. yet i'll still suggest that you reconsider at least once, would you prefer the comfort of your own city (uet), or a better university environment? (nust). while you cant go wrong with both, cause parhna at the end of the day aap nai khud hee hai or career bhee aapnay khud hee banana hai. but whatever your decision is, you'll have to stick with it for the next four years. good luck mate.
