What's the best way to improve my public speaking skills while studying online and working a part-time job as a tutor?

I totally get it, balancing a part-time job, studying online, and taking care of family can be overwhelming. It's great that you're thinking about improving your public speaking skills, though - it's a valuable skill that can benefit you in many ways.

First, I'd recommend checking out online platforms like Coursera, Udemy, or edX. They often have courses on public speaking that you can take at your own pace. You can also look into online speech coaching services or one-on-one coaching sessions, which can be a bit more expensive but might be worth it if you need personalized feedback. One course that comes to mind is "Public Speaking" by Dr. Pamela A. Ebesu Dubose on Coursera - it's a great introduction to public speaking and has a lot of practical tips.

As for practicing at home or with a small group of friends, try recording yourself speaking and watching the video to identify areas for improvement. This can be a great way to get used to speaking in front of a camera, which is a common requirement for online classes and presentations. You can also practice speaking with a friend or family member who's willing to give you feedback. Even just 10-15 minutes of practice a day can be beneficial - try setting a timer and speaking on a random topic or topic you're passionate about.

Lastly, consider joining online communities like Toastmasters or online public speaking groups on Facebook or LinkedIn. These groups can connect you with other people who are also working on improving their public speaking skills, and you can learn from their experiences and get support.
