I am moving down the levels doing everything that is bot pre-algebra before moving on to pre-algebra etc building a solid foundation so I can be better at painting, drawing sketching and most important using blender software to animated, sculpt etc, I am going sown the maths by subject and maths by grades to better myself doing all the practises and watching all the videos and then doing the math missions on the maths world the math by subject section that does all the math missions at ones, but the question is are the practices important or is it the videos and the math missions that are most important?
