I going to write 4B exam anyone have any better questions and answers l am little nervous

Hello Everyone, i just want to ask for your help. I’m really having a hard time doing the math problems. I couldn’t find the right formulas for the 4th class exam. I hope you can help me where to find the formulas for the review. (Specific heat, determine the length, average speed, more like these questions) thank you!

Hi Everyone, I just want to know how did you prepare for your exam. Any tips you can give will be appreciated. My exam will be in 3 days now and I'm nervous! hehe Thank you!
