[@thaoanh5094]

Omg can u tell me how you reviewed for the test of chemistry? Im about to take the exam next month and i don’t know how to get high score 😭 im scared

[@yoonpopoaung21]

Firstly, I watched this whole syllabus video and made sure that I had covered the whole syllabus and understood it well. After that, I practiced for past papers. As I didn’t have that much time, I just watched past paper solving videos instead of solving the problems on my own and made sure that I understood the solutions. The most important thing is that you understand the lessons and practice past papers as many as you can and you need to remember the important things like formulas, reactions, tests, etc. Don’t be worry too much, you can do the best.

Hello Ms. Hazel. I just got my IGCSE score back for my Chemistry (0620) and Biology (0610) exam. I am an independent homeschool student and I have used your videos as revision for my chemistry and biology exam. I just want to say thank you; with your videos and help I got an A on my chemistry exam and a B on my Biology one. Thank you so much, you are a godess!

[@SciencewithHazel]

Amazing! Congratulations!!

Been stressing over chemistry for the past year and now finals are coming up. You are a life saver, this video is helping me so much!!❤ I love the easy to follow descriptions and the words on the screen for me to note down😊

hi hazel, i am a private candidate and i sat for oct/nov session for igcse. i only used your videos for preperation and i covered everything under 3 months and i got an A* in chemistry and physics and an A in biology thanks alot for posting such content for which any other person would charge but you do it for free thanks alot .i appreciate your hard work from the bottom of my heart

[@user-gu9lw6bf6c]

this is my commitment to work smart and hard for my IGCSE in Feb March and get an A* in all my subjects. i have 2 months to go from C's to straight A's. i tend to procrastinate😅😅

btw guys, electrolysis of aqueous solution concentrated aqueous - halide formed in the anode dilute aqueous - oxygen formed in the anode i think the video says that always halide is formed...i think it needs correction :)

[@nufailanoon]

Even though I'm not rushed like some of the viewers, my exam is in more than 50 days, but I thank you so much. Truly, thank you. You don't know how many students you saved from failing. Some of us, like me, love chemistry and understand it but our teachers aren't good at explaining

[@AtarwaNoUcom]

thankyou so much, i used this video during my 9th final and got a B. the intersting part is that i started studying chem for the first time basically in 9th, now im also using this for my upcoming board exams.(india)
