grades to get into biology chemistry and psychology

Y13 student here. I’ve been struggling with incompetent parents, adhd symptoms & mental health issues too. It’s hard to stay committed when your brain isn’t functioning like everyone else and then you have environment factors that hold you back. You said mocks so I’m assuming you’re a year 10 student, you have a whole year to turn those grades around and get what you want. I know again that motivation is so difficult when we’re literally struggling to live but build it up bit by bit, do 30 minutes a day then gradually 45 and then 1 hour. Tell yourself that if you want to study those subjects you have to work harder. GCSEs are quite easy to turn around you just generally need to lock in. Those requirements are there because schools know that dealing with a levels aren’t easy, truthfully speaking, I achieved all 7-9s at GCSE and I have been struggling with A-levels as though I was a 3 student. You mentioned that the school in your area require 6s, perhaps try and see if there are colleges/schools a little further from you that may accept the grades you have? A college at my city accepts 5 GCSEs at grade 4 or higher to study A levels. The commute may be difficult but again if it’s something you want you just have to put your mind to it. I see you and you’re not alone. With the school environment, distance yourself away from those people who are negative. Alone and driven is better than having friends who are bringing you down, maybe try and spend some lunches at the library catching up on homeworks and etc. I would say reach out for help but as someone in your shoes, I know how hard it is do so and therefore do the best you can to help yourself, this is your life to save and your life to live.
Keep going.

no im year 11 sadly but thanks for the advice <3
