To find out if there was negative marking in the 2012 NUST undergraduate admission test, you would need to:
* Contact NUST directly: The best source of this information would be the admissions office at NUST. Contact them through their official website or phone number.
* Search for past papers/information: Try searching online for past papers or admission information from 2012. Sometimes this information is available on unofficial student forums or websites, but verify its accuracy with NUST.
Keep in mind that even if you find information online, it's always best to confirm it with the official university source.
