Hello, world! This is CS50x 2019.

Are you a student in high school who'd like to take CS50 for AP credit? See CS50 AP.
If you started CS50x before 2019 but didn't finish, not to worry. Scores from past years will be automatically imported into CS50x 2019 (by the second week of January) so your progress won't be lost! However, moving forward, you must submit CS50x 2019's problem sets.
If you didn't submit any problem sets last year, resume your studies with Week 0 and Problem Set 0 of CS50x 2019.
If you submitted Problem Set 0 last year, resume your studies with Week 1 and Problem Set 1 of CS50x 2019.
If you submitted Problem Sets 0 and 1 last year, resume your studies with Week 2 and Problem Set 2 of CS50x 2019.
If you submitted Problem Sets 0 – 2 last year, resume your studies with Week 2 and Problem Set 3 of CS50x 2019.
If you submitted Problem Sets 0 – 3 last year, resume your studies with Week 3 and Problem Set 3 of CS50x 2019.
If you submitted Problem Sets 0 – 4 last year, resume your studies with Week 4 and Problem Set 4 of CS50x 2019.
If you submitted Problem Sets 0 – 5 last year, resume your studies with Week 5 and Problem Set 5 of CS50x 2019.
If you submitted Problem Sets 0 – 6 last year, resume your studies with Week 5 and Problem Set 5 (but you may skip psets 6 & 7) of CS50x 2019.
If you submitted Problem Sets 0 – 7 last year, resume your studies with Week 5 and Problem Set 5 (but you may skip psets 6,7 & 8) of CS50x 2019.
If you submitted Problem Sets 0 – 8 last year, resume your studies with Week 10 and the Final Project of CS50x 2019.
