Wow.. A lot happened whilst at work and sleeping xD. To answer everything, I understand that there are a lot of good free resources for Maths and Sciences. However, the benefit of having one website is that there is less distractions and also I know what I'm getting with the product. Furthermore, my sixth form that I will be attending is one of the best in the country. However, I really need these A* so I'm willing to put the money since i can fund it. Just want to quickly mention though after having a look at Tailored Tutors, I will buy Tailored Tutors for Maths and Chemistry then Just Physics with UpLearn. The reason is that the courses that Tailored Tutors better fits the way I learn and it is really easy to just get on with the work (Which is the main problem I have with free resources. They seem to take so much energy just to start revising and the way that some of the online teachers teach makes me zone out then I end up playing a game or something which is counter-productive. The only YT maths teacher that hasn't left me uninterested so far is The GCSE Maths Tutor. However, as inferred by the name they don't really do A-Level Content). But, I will wait until I get my GCSE results back before I invest in anything first since I'm currently just scouting out revision and learning resources before I begin my A-Levels.
