 A suggested weekly schedule for each month for the CS50 material is:
 
 -   Week 1: Watch "Lecture" video (2.5 hr)
--   Week 2: Watch "Shorts" (\~6 x 10-15 min videos that expand on topics in the lecture) and do one or more of the [additional practice](https://cs50.harvard.edu/x/2024/practice/) problems for the corresponding week

 -   Week 3: Watch "Section" (~1hr video going beyond the lecture) and do one or more of the remaining additional practice problems
 -   Week 4: Meet to share solutions to the practice problems. Optional: Do "Problem Set" and submit if doing course for credit, or if you want to receive an automatic grade to check your progress
 
-**Note: we may update the suggestions about which problems to attempt when the CS50 course for 2025 is published.**

 The additional practice problems are often harder than the problem set, 
 however we suggest leaving the problem set till after the meetup and attempting 
 this independently (this is expected if you are doing the course for credit).
 
-There is the option to do further study towards a free [certificate](https://cs50.harvard.edu/x/2024/certificate/) from Harvard or a verified certificate from edX (~200 USD, financial assistance program available on edX). See the CS50 website for details.
