 Welcome back to the session on Letic. In session 36, we created our first presentation in Beamer and explored the different themes and color themes which we can use to style the presentation slides. Each slide is denoted by a frame and so to create a slide, we write slash begin frame and slash end frame. In session 37, we added some basic blocks, alert block and example block, each of which has different styles. We finally divided the content on the slides into multiple columns. Session 38 was exciting in which we added some effects of animation in our slides using the commands like pause, onslide, etcetera. In session 39, we added some basic information and logo to our slides. Session 40 is one of my favorites. Using the commands covered in it, one can design beautiful presentations with which one can easily fall in love with. In the last session of the topic, we understood the concept of aspect ratio and how we can change it. This brings us to the end of the course and we hope that you enjoyed it. We also hope that you can now concentrate more on the subject rather than the formatting, especially while submitting your papers to conferences. It was indeed a pleasure in interacting with you on the discussion forum. We at IT Bombay, thank you for participation and efforts.
