00:00:00,000 --> 00:00:01,300
SPEAKER: You certainly can.

2
00:00:01,300 --> 00:00:04,570
The course does change a little bit
each year in terms of its problem sets,

3
00:00:04,570 --> 00:00:06,570
in terms of how we present
some of the material,

4
00:00:06,570 --> 00:00:09,640
but the underlying syllabus is
fundamentally going to be the same.

5
00:00:09,640 --> 00:00:12,015
So if you want to fill in
some gaps in your knowledge,

6
00:00:12,015 --> 00:00:14,640
refresh yourself indeed on some
of the topics, then absolutely.

7
00:00:14,640 --> 00:00:16,470
By all means, take the course again.

8
00:00:16,470 --> 00:00:19,900
But I would avoid getting stuck
too much in a loop, so to speak,

9
00:00:19,900 --> 00:00:22,800
of doing the same material again
and again, as opposed to broadening

10
00:00:22,800 --> 00:00:25,830
your horizons and taking some other
class, or better yet, tackling

11
00:00:25,830 --> 00:00:28,890
some personal projects of interest
that you can actually apply what you

12
00:00:28,890 --> 00:00:32,360
learned way back when in CS50 itself.

13
00:00:32,360 --> 00:00:37,000
