Detailed walkthrough
The first stage of this quest is to make your way to the X-8 Research Center, and utilize the terminal you find to the left of the locked door. This being your first time out, there will only be the Basic Institutional Data Test Retrieval test available, so select that option when ready, and make your way inside.

Once inside, you will see that the testing area is in the shape of American High School, the place where Dr. Borous's mind first got twisted into the arsenic stuffed pretzel it is now. The doctor himself will talk over the loudspeaker, proclaiming himself to the "First Doctor Principal" of the school, and describing the many dangers that await you in here. When ready, go and open the door to your right, and then immediately dive for cover, as a Hall Monitor laser turret will open fire as soon as you come into view. Go through the classroom door across the hall, and look for the terminal on the wall near where you came in. You can use this to deactivate the turret or reconfigure it's targeting parameters.

Once that's done, open the door leading into the next classroom, but be wary. Cyberdogs and robots stand ready to attack you, so defend yourself accordingly, Once they're all down for the count, move to the terminal and desk, and access the data. The next data file is in the Library, which is done the hall to the left, so make your way there and prepare to deal with the cyberdogs guarding the place. When things have settled down, you'll find the terminal in the far left corner of the room.

Only one more remains, and that's upstairs. Return to the central hallway, where the first Hall Monitor turret was, and look for the door marked "Stairs". Open the door and move up, but watch out as you climb to the top, as another Hall Monitor turret will take exception to your lack of a hall pass. Fortunately as Easy terminal stands nearby, and you can turn off the rain of deadly visible light. The 3rd and final terminal stands on a nearby desk, and once the data is obtained you'll be directed to leave the testing area.
