You have the right number of slides (12 slides)  for an 11 mins talk but you extended your talk by almost 11 minutes. It’s a way over time. Practice more and think about what you want to say for each slide. You spend way too much time on a couple of slides.

Content looks good on the slides.

There are few comments about the timing and cosmetic changes as follows:

There is a mixed match of fonts on several slides. Make sure you are using the same font throughout all slides and for all bullet points except for equations or special characters

Slide 2: Tex size is too small to read clearly

Slide 3: You can go little faster on this slide to save time

Slide 4: You spend more than 3 mins on this slide, keep it under 1:15 mins

Slide 5: Be precise when you talk about the slide. Spent 3 mins on this slide

Slide 6: Spent about 3 mins

Slide 7: two different fonts than the original and the text size is small. Spent 2:20 mins

Slide 8: time spent 2:40 mins

Slide 9: 1:27 mins

Slide 10: You are using a different font than the original one, Took a couple of long pauses during this slide. Slide time 1:10mins (Here you spend the right amount of time)

Slide 11: 1min

Slide12: 1:50 mins

In general, spend an average of 1 min on the slide. Please practice and record the video again and stay under 12 mins.

Good Luck!
