I need help concentrating in maths and help on sets 💩💩💩
My advice would be sit next to a generally quite student in the class, if you have difficulty concentrating. Aim to finish the questions allocated for homework in class, which consequently allows more time for revision when you get home. Hope this helps.
Practise exam questions and revision questions at the end of the chapter. Also practise questions which you found difficult( eg. Problem solving using sets) practise practise practise.
Always try and draw a venn and fill in what you are given.
I think the trickiest part to get is the intersection... once you can fill that in everything usually falls into place.
