Coursera has some of the best sustainability and environmental science courses. I completed one from Yale University, and it helped me understand climate action deeply. The platform is easy to navigate, and learning at your own pace is a huge benefit.

Unacademy offers good classes for students preparing for UGC NET or civil services, especially in topics like environment and ecology. The live classes are clear, and notes are very helpful. A few recordings had audio issues, but overall it's a reliable platform.

A Good Blend of Fun and Learning The activities are fun and keep children engaged. My daughter loves storytelling and picture description tasks. I just wish the feedback after each session was a bit more detailed.

Steady Progress with Friendly Trainers My daughter takes her classes regularly, and I’ve seen her grow more expressive. The trainer makes her feel comfortable, which matters the most. A few sessions got rescheduled, but it wasn’t a major issue.

Suitable for Building Public Speaking Basics PlanetSpark helped my son understand the basics of public speaking, like structuring thoughts and using expressions. He’s still building confidence, but at least he’s on the right path now.

I joined to improve my fluency for work presentations. The trainer was polite and corrected me without making me feel awkward. Some sessions went slightly fast for me, but overall I learned a lot.

PlanetSpark has helped my 8-year-old become more expressive. Earlier he used to answer in one word, now he forms sentences properly. A bit more writing practice would also help, but the speaking activities are excellent.

Adult Course Helped Me Speak More Fluently I took PlanetSpark’s adult public speaking program. The trainer gave me practical tips for interviews and presentations. I still get nervous sometimes, but the fear has definitely reduced. Overall, a good investment for personal growth.

Byju’s video lessons make understanding complex topics much easier. The visuals and animations help kids grasp concepts quickly. The only drawback is the course cost, but the content quality is strong.
