Your answers and pdf solution helped raise my grade from failing to D to A* and I really appreciate your website has the detail solution of IGCSE Extended Mathematics (0580). Solving the maths problem was real pain for me, so I consider your website to be the sole reason I secure higher grades in IGCSE. Thank you.

The David Rayners PDF’s solutions were extremely helpful. You can use them over and over and solve them to confirm the answers without taking the help of a tutor. The PDF explained the details step by step beautifully and provided details on performing the algebraic manipulations. My Maths teacher often moved through the material very fast in class. The PDF’s allowed me to review areas I found difficult as many times as I needed. David Rayner Answers was a wonderful learning tool for understanding IGCSE Maths.

As a IGCSE Chemistry Instructor when I started my carrier for the first time at ABWA School, I found this resource incredibly helpful for me and my students and I highly recommend it to anyone using IGCSE Chemistry Answers website. All the best for IGCSE Chemistry Team.

I just wanted to tell you how grateful I am for what you’ve done with this website. I’m a student athlete, and I go to school entirely online because of my training schedule. I have maths as my subject which I found really tough, but I have to teach myself the material with the textbook as my only complete resource. On the rare occasion I have time to work with a tutor, they are rarely able to help me understand. I love learning and school, but I’ve always struggled in science so I was sure this year was going to be brutal. Thanks to you, as it was a nightmare to complete my Maths assignments & Homework that used to waste loads of time. I can watch one PDF’s, followed along, and understand the rest of my assignment no problem. Again, your work is much appreciated. I bought a yearly plan within a few minutes of finding your site.
