yes i wuld also suggest to avoid coaching centres for Inter
get private tution for Physics / Maths / Chemistry
try to get the same guy to teach all 3 or alteast 2 of them
dont waste much time running all over the city for independent tutions
Adamjee waghera koi dream shream nahi honi chahiay for Inter ur college means nothing
for NED recently the percentage requirements have shot up waay too much
Astronomy waghera bhool ja ajeeb chawal field no scope
if u want Aeronautical only NUST is offering it as far as i know
if ur aiming for NED u shuld be aiming for Electrical / Electronics / Mechanical (or Civil IF u have interest)
these r the mother fields which u shuld be trying to get ur Bachelors degree in
u can later on do masters in anything specific field u like hell even Astronomy S:
