Find Lab Access Card
After entering the Malden Middle School, turn to the door behind the bars leading to the basement. There you will find a group of shooters and turrets. This is also where the quest will start.
Run to the elevator ahead. Ride down to lower floor. There you will have to face another group of opponents. Keep going through the main corridor. After a while you will reach a large dining room. Enemies are waiting for you on the balconies as well, so be careful.
Once you clean the dining room, go to the northwestern part of the ground floor, to the locker room. Walk through the door and go to the end of the corridor. Turn left there and use the stairs. Turn left once again. You should see a model of the city. Enter the building ahead and walk to the first floor - the enemy you will face there will have the laboratory access card.
Find Admin Access Card
Now go back upstairs. The closed door on the left can be opened now. You should turn right behind the door, into the door with the "overseer" sign. However, you need second card in order to get there.
Turn left behind the door and go to the end of the corridor. Enter the small room ahead. On the desk under the window you will find the Science Bobblehead which will give you one additional attempt when guessing password to hack the terminals. One of the bandits in this small room will have the overseer's access card. Go through the same road to the closed door and use the card.
In the room with the "overseer" door you will find, in addition to the strongest raiders, the Grognak the barbarian magazine. The door behind which the item can be found will be opened by using the terminal on the office. Checking the terminal is also the main objective of the quest, once you do it, the task will end.
