I wrote my Chemistry exam today. Studying has been hard because Load shedding this side is ridiculous and everything from my textbook to my study schedule is on my laptop and my tablet. I don't think I got marks that are out of this world, but I am proud of myself. I didn't skip a single question and I even had some spare time, I didn't cry or skip large sections. I am way more optimistic then I was with my Physics paper. You videos helped me so much, I hardly listen in class, because I don't like my teacher's teaching style. I think I have an opportunity to improve and even get a 70% for my end of year marks. Last year I got about 30% as my final mark for Physical Sciences (I transitioned from Cambridge to Caps) I think what's nicer this year is that I get to start the school year from the beginning with this new curriculum and I did a lot of the things I am doing now in my IGCSE. Thank you from your videos...thank you so much.

Hi Inolofatseng, I'm elated to hear that you're improving. I still want to appeal that you try to listen to your Science teacher. My videos are to supplement what s/he is already doing in class and not to serve as a replacement at all... It's a collaborative effort aimed at helping you move forward with your future. Is it possible for us to aim for 80%. Let's do it... I know you can 😊
