Hello again! Now you're extending the lines correctly, and the accuracy of your guesses is pretty good already as well! The main thing here is that your lines are still wobbly. Your first priority with lines is to make them confident and straight above everything, so focus on that first and don't worry if you need to sacrifice accuracy to achieve it.

Here's one example applying the concept, top line is a level 1 line, and bottom line is a level 0 line. This is because a confident line will always be better than a wobbly line in these exercises. This includes boxes as well, so make sure you approach every single line of every box like this.

Something that can make it easier to draw more confidently is drawing a little bit faster, so try to experiment with speed until you can draw lines fully confident.

Other than this overall as I said earlier you've done a good job, so I'll mark this as complete. Just make sure you focus on drawing confident lines above everything even if you need to sacrifice accuracy and good luck on the box challenge!

Remember as well that from now on you need to do warmups before every session, and keep up the good work!
