hi, so i just bought this game and i've played a bit, but now i'm on a quest where i need my Science to be at 50, and i only have 25 atm, since i dont really care for that.

so what i need help with is where to find, and how to use, like magazines or something just to put that up to 50 just for a short while.
thanks

The Wiki to the rescue.

In short, this magazine will buff your Science by 10 (20 if you have the Comprehension perk). I'm pretty sure that magazine buffs don't stack (i.e. reading two magzines at the same time won't double the boost you get).

If you have Comprehension, you could take some Mentats to gain the extra five points you need to reach 50. That buff will stack on the magazine buff.

For a permanent boost, you'll need to find copies of the http://fallout.wikia.com/wiki/Fallout:_New_Vegas_books_and_magazines

thanks man.

so the best option is to get the Comprehension perk ?

it's a great perk, I never do a playthrough without it.
