year 12 summer

i am screwed
I did my year 12 mock and I got BBC in maths economics and chemistry. I really want to do a degree in economics which requires an A* in maths and an AA in the other 2 subjects.
PLEASE tell me what to do during the summer to make sure i get my predicted grades up because i am genuinely passionate about doing economics but my brain blanked out so hard while doing mocks. I have my new mocks in september and im so committed to doing anything to make sure i get those predicted grades.
any tips for revising those subjects, how many hours and how to make my application competitive will be so much help

i’m not an economics or chemistry student but i can speak for maths.
I did every single AS level past paper for my exam board in preparation for my end of years. I also do further maths which definitely helps my maths ability but i understand this isn’t an option for you.
I would say ensure you understand the key concepts behind everything you’re doing as this isn’t something you can cram in the day before and test and this aspect is the most important to be good at maths (and i assume chemistry). Instead of just memorising methods and formulas and information, go in depth and spend time understanding why what you’re doing works.
For example,
why can we take derivatives of functions and what does the derivative actually mean?
Why is the equation for a circle (x-a)^2 + (y-b)^2 = r^2 ?
I don’t doubt this applies to chemistry and econ too.
If you spend time understanding the concepts behind a topic instead of memorising methods, when it comes to applying your knowledge to never seen before questions, you will understand what you have to do and WHY because you know WHY doing that particular thing works in that scenario.
Once you grasp this, do every practice question under the sun. I did just about every single question in my AS maths book. All exercises, mixed exercises, review exercises plus the past papers.
The absolutely best way to get better at maths, tried and tested, is to do loads of questions. If you don’t know how to get an answer or why something works, ask for help from a peer or your teacher.
MadAsMaths website has good questions though it’s a bit confusing to use as a website.
I’m not sure how effective flash cards are for you but I use them for physics and I got an A* in my end of years. Make sure if you use them though, that you write them by hand yourself and allocate time each day to read through them.

If you have mocks in September, and you know they will be used for UCAS predicted grades, all you really need to do is to get A*s on those mocks.
For maths, keep doing past papers, ideally from your exam board but if those are all done anything works (edexcel and madas have a lot). If you lose marks on a question, do practice questions on the topic, ideally until you can do questions at or above the hardest difficulty allowed on the A-Level. There's no shortcut which avoids doing a ton of practice. This probably applies to your other subjects too. You have 2 months or longer to do every past paper and redo every topic you need to. Thinking about it in hours is pointless because the time required to work up to an A* is different for every person.
Realistically unless it's Oxbridge or LSE, getting the grades is all you need. If you've written some particularly nice essays or competitions you can put those on your personal statement, and you should try to apply that skill to A-Level Economics. For the summer you should be focused on getting your predicted grades up to standard, if you miss the requirement by one grade, it's over.

Not all Economics degrees require an A* grade in Maths - or even A*AA.
Undergraduate - Economics subject group - University of Liverpool - AAB
Economics, undergraduate courses : University of Sussex - ABB
Economics | Nottingham Trent University - BBB
etc.

You are defo not screwed, I got a B in chem and C in maths in end of years and improved massively (I obvs don’t know exactly how much yet though haha)
Chemistry:
Any concepts that you don’t understand ask your teacher or if they don’t make it better then YouTube (ma Chem guy, free science lessons)
I made mindmaps and flash cards to help me condense and memorise the info at the end of each topic in preparation for the end of topic tests (if you do that)
Past papers galore, I did almost every pst paper in preparation and it helped the most out of anything, it will be hard and frustrating to start with but after you finish one, mark it thoroughly abd harshly and then use a walkthrough on yt to properly understand your mistakes (I used a level cookbook a lot)
Maths
This was never my strong point at all but it finally clicked about a month before my exam when I started to put effort into it, make sure you get the basics, mr Bicen is a legend on yt and has chapter summaries for edexcel and has some paper walkthroughs (mr atsbury is good for walkthroughs too!)
Maths genie is Amazing for topic questions and do as many as you can until they get boring and youre getting majority to everything right, tbey have model answers too which are incredibly helpful.
I hope this helps and more than anything start early and do little and often it will show in the results, trust!
If you have any questions about chem and maths lmk and I’ll do my best to answer them good luck!

Did you have yr13 September mocks to boost Predicted grade for early applicants ?

No, mine Wete in January snd didn’t go to plan but grades had been discussed before then, I was predicted A*AAB in the end but never performed well in chem and maths mocks, you’ve gotta prove yourself in class by answering snd asking relevant questions so the teacher can see your willingness to improve

I mean you can request mocks for early applicants surely

Thank you for this! Did you happen to do TMUA? Some of the courses in London require this and I haven’t really started prep which is probably bad - if you have tips on this as well if you have done TMUA or anything adjacent that would really help
