Good luck! I did the Beginner 1 and saw that type of gain so it's doable!
Sans's beginner study plan

Constructive takeaway:
1. Double check before a move (check if opponent can fork/create opportunity).
2. Double check to pick on captures that are advantageous

Day - 4 (black)
Positive takeaway: Used tactics such as forks to gain an advantage
Constructive takeaway: -> Use checks, captures and threads method to find best moves
-> Analyze intention behind enemy's movements and possible responses

Positive takeaway: Capitalized on forking tactic and stuck to advantageous exchanges. Developed my pieces earlier than my opponent.
Constructive takeaway:
1. Although good tactics were available, scan atleast twice to see other possible options that are better forks/pins/tactics
2. Castle the king once development has proceeded.
