uni courses, economics and psychology

Please help!!!
I've always changed my career path multiple times from medicine to economics to psychology. But I really need help. I currently study economics business and math, I absolutely love economics especially behaviour and I find the theory really interesting. However, my math is not looking good i'm predicted an AAD and I will likely resit during my gap year.
I want to do psychology because I find it really interesting and Ive had a psychologist myself who has helped me so much. It's just a subject I don't think I would ever get sick off. And I would love to do research psychology more than anything. However, I've learnt how hard it is to get into a doctrate program and I really dont want to risk it even though I wouldn't mind reapplying.
Alternatively I would love to do economics and I'm fine putting more effort into stats to strengthen it, but I honestly mostly enjoy the theory but in terms of future jobs its a great undergrad.
I was thinking of doing an undergrad in economics and then maybe a doctorate in research psychology as if I dont get into a doctorate course its less risky as economics undergrad is a great qualification. My dream job would be research psychology so a bps accredited undergrad in not needed. Please let me know I would love to know your opinion and experience.

I currently study economics business and math,
I'm not a fan of the eocnomics and business combo - some universities don't like the combination because the subjects are too similar (but anyone and everyone who studied both subjects can vouch that they are completely different). If the entry requirements of the specific degree that you want to study specifically say they want a well rounded applicant, you're out of luck. I would recommend dropping business or economics for something else as the key subject for economic degrees is maths.

Economic degrees are generally not walks in the park. If your maths isn't up to scratch, you might have a bit of a difficult time. The key areas of maths concerned are:
If you're fortunate to do the more challenging mathematical economics modules:

If you need to resit your maths during a gap year, do so. It would really make a difference to the universities that you can apply to. Aim for at least an A where possible, but you should be getting A* for the top end unis.

Have you thought about doing a joint degree in Economics and Psychology? They are out there:
https://www.essex.ac.uk/courses/UG01300/1/BSc-Psychology-with-Economics (BPS accredited but not mathematical, which can be an issue if you want to go into economics)
https://undergraduate.degrees.ed.ac.uk/index.php?action=view&code=CZ81 (BPS accredited and mathematical)
https://www.strath.ac.uk/courses/undergraduate/psychologyeconomics (not accredited and not mathematical)
https://warwick.ac.uk/study/undergraduate/courses/ba-bsc-economics-psychology-philosophy/ (not accredited but mathematical)
https://www.abdn.ac.uk/study/undergraduate/degree-programmes/565/LC18/economics-and-psychology/ (accredited but not mathematical)

I think you would need to revise your assumptions. A degree in economics is only required for roles as an economist (if that; people with quantitative degrees seem to be able to get the role as well). It's usually not required for any other jobs.
If you are thinking along the lines of finance, accounting, business roles, they typically accept graduates with degrees in any subject or people with no degrees, since a lot of the roles will require specific professional qualifications for the specific roles and these professional qualifications tend to require no prior qualifications (not even GCSEs). Those that do tend to ask for quantitative degrees (CQF) or a degree in any subject (CFA). You can do the actuary qualification without a degree, but a quantitative degree can help your application. None of these roles will require a degree in economics, and an economics degree will only help if it's mathematical.
I was thinking of doing an undergrad in economics and then maybe a doctorate in research psychology as if I dont get into a doctorate course its less risky as economics undergrad is a great qualification.
I think this is a little misguided. To do a doctorate in psychology, you either need an undergrad in psychology or a postgrad psychology conversion course. You can do a psychology conversion course right after an undergrad degree in economics should you like.
It's usually recommended that you do a master's in psychology on top to strengthen your doctorate application.
As mentioned above regarding an economics degree, it's not as widely required as you may think. In fact, it's not necessarily that much better than a psychology degree for job applications (you can get in most of the same roles as you can with an economics degree - the jobs that you might struggle a bit with are those in economics, quants, and actuary.
My dream job would be research psychology so a bps accredited undergrad in not needed.
As you mentioned that you like economics as well as psychology, just to throw it out there: have you considered looking into behavioural economics, economic psychology, and experimental economics - these are applied psychological theory into economics situations. See:

Thank you so much, I've found this really helpful.
But I decided to just stick with economics as I really enjoy it a-level, would love to go into policy making, research or consultancy. Psychology is not convenient and getting into masters or doctorate is mostly luck but going off what I know I think Economics is safe as it is my favourite subject. I'm not exactly bad at math I have just been extremely lazy I have gotten 70% on pure recently but cause I don't even bother revising mech/stats 10%. I will likely have to resit to get an A which Is fine cause I'm taking a gap year anyways. You mentioned that Business and Econ is not a good combo, I was wondering what other subject you would recommend. I'm applying to mostly Russel group that require around AAB and no TMUA for their course. My friend applied to Russel group unis with the same exact subject combo and got accepted her predicted were A*AA with an A* in business. I'm guessing I will get an A* in business and an A in Econ and probably have to retake math to get an A or maybeee A*. Do you think I will be fine? or do u recommend anything else.

Hi there,
From what you've said I think you've made the right decision. Econ can open a lot of doors for you post-graduation (a masters if you want, careers in banking, finance, data modelling or investments, even behavioural economics or environmental psychology), and although psychology is a broad degree which you can also do a lot with, you would need to a lot of extra studying to become a research or practicing psychologist and jobs at the moment are particularly competitive.
I don't think all unis will look down on a Business/Econ combo (you would have to look at specific entry criteria), but I would emphasise that Econ degrees are really quite mathsy and so it would be fab if you could spend extra time this year really working to boost up your maths grade. Make a commitment to yourself, perhaps to do an extra hour to an hour and a half's maths four times a week for the next couple of months and have a word with your teacher to see if they'd be willing to boost your maths PG to a B or an A and aim for something higher. Trust me, if you put in the work now it'll put you in such a good place for your Econ degree!
I hope this helps and wishing you the best of luck!
