Thanks for letting me know about Security, updated it to the 4th point.

As for Beckett; he did teach the 5th Scholarship point for free with UP+ during my playthrough.

Good guide!
Just two things I want to add/ask:

1.The security book from the Museum gives a skill point to either 3 or 4. So to maximize your exp this should be the fourth point. (tested on UP 11.5)

2.Beckett should not give Scholarship 5 after the Italian Diner quest? I could not test it myself yet so I just copy the part out of the UP walkthrough:

+1 Investigation [1-3] (After the Giovanni mansion)
or +1 Scholarship [1-4] (For all clans)
or +1 Humanity [1-5] (For all clans)
or +1 Discipline [1-3] (For Gangrel players only)
[+: or Celerity [0] (For Gangrel players only)]
[+: or Animalism [0] (For all except Nosferatu)]
[+: or Fortitude [0] (For all except Ventrue)]
[+: or Protean [0] (For all clans)]

Hope this helps. Either way, thank you again for making this guide!
