I just wanted to come say that you're videos are short, sweet, to the point and explains everything really well according to the GCSE and CSEC syllabi and they have been a MAJOR help for my students and I since we have all went fully virtual with school. All my students (advanced or not) have found your videos super helpful and I want to thank you for the work you put into these videos. It's much appreciated by students in the Caribbean. I hope you see this comment and the others because u are one of the best channels on youtube in terms of assisting secondary school students in their subjects. Hope all is well with you during this pandemic despite everything. I wish you all the best. 🇹🇹#868
