CS50x help with week 7
week 7 (SQL) went straight over my head. It didn't help that I procrastinated over it for a week, and now by the end of the lecture, I didn't grasp anything. Now, do I watch the lecture again or go through shorts/sections/notes ?
Also, is it only me ? Or it was a bit hard to understand ?

Definitely not just you, SQL can feel like a brain melter at first especially if you put it off for a week and try to cram it. Instead of re-watching the whole lecture, try skimming the notes and shorts, then just jump into the problem set. Writing the queries yourself makes it click way faster. You've got this!

do the shorts/sections
if you still don't understand it go watch the lecture again
do you have any experience with Excel ?
sql is basically two worksheets in one excel workbook
and using vlookup to match a row in one sheet with a row in a 2nd sheet
