A level choices - too weak?

They look hard to me!
Had she looked properly at the Economics? It might have more maths content than expected.

Econ and Politics A levels do fit well with History. However, they are also 'unknown quantities' in that they are (usually) not taken at GCSE.

One of my DC considered both those subjects for A level and found it useful to review past papers and some of those CGP study books to get a feel for the syllabus and the exams. They did not go forward with the subjects in the end; your DD might take a different view; as always, 'information is power'.

Ultimately it is about the trade-off between likely grades and doors kept open (if the latter matters). Better AstarAA in History, Econ and Politics than AstarBB in History, Maths and Physics. However, AstarAA in History, Econ and Maths would keep more doors open but A level Maths is a material step up and if your DD is realistically likely to attain an 8 rather than a 9 at GCSE, then the likelihood of securing an A in A level Maths is diminished.

My ds is in the middle of his A-level exams doing these 3 subjects and I would challenge anyone to tell him they're not hard at the moment! The amount of work he has done is phenomenal.

He has had offers from 3 Russell group universities plus Bath (his first choice) which is top 5 for his course and only admits 10-20% of applicants.

I fail to see how anyone can say they are not 'hard' enough - she should choose the subjects she is interested in and which will lead her in the direction she wants to go. Stuff what anyone else thinks!

No point doing A-Levels she doesn’t like, but if she wants to do Economics as a BSc she will need maths. There is a lot of maths and it is more advanced than A-Level maths.

No point taking STEM subject if you don't want a STEM career. Obviously she could take maths instead of politics if she wants to focus on economics, but if she's not really interested there's no point pursuing it.

There's no point in taking STEM subjects then.
People saying this are obviously out of touch.

History is the hardest essay based A level. Really hard. The others are also fine. What do people think she should be doing, STEM? I mean, if that's neither her aptitude nor interest what is the point in making that comment?

How about History, English and Politics?
She could do a History degree then go for a career in Law.

Ah we were ok until you said lucrative career!

If she is interested in economics then would she consider maths? If she ended up loving econ enough to take it at uni then maths is needed really.

Have a look at uni websites for course ideas - the worst thing just now is to close doors she later wants to keep open.

No such thing as an easy A level @dinomirror . If she is interested and will do well then they are good choices.

What’s the thinking behind econ tho? An econ degree usually needs maths tbh so she should be aware of that.

Does she want to go to uni? What might she study? If history is a passion then happy days. Otherwise (and this is the only caveat from me tbh) politics and economics of themselves don’t open any doors. If she was unsure about uni options she might like to take something like geography or MFL or Eng lit or maths which would keep more doors open. But the choices otherwise are fine.

What does she want to do next?
In many cases, unis/employers will be looking at the grades not the subjects at A Levels (except to study a particular subject) so she would be better with three "easy" As than three difficult Bs.
If she wants to continue with economics though, I think she would need maths.

Ds took these A levels. Got 5 offers from Russell group unis, all in the Sunday Times top 20. He got a first from the LSE.
Yeah they were hard. People saying otherwise have absolutely no idea. He did also take philosophy.

Ignore the people who seem to sneer. Good choice of subjects. The most important thing is to do subjects she actually enjoys.

Look at informedchoices.ac.uk which is created by the Russell Group universities.

Those A Levels look pretty respectable to me.

Believe me, History is a very challenging A level indeed. It's not just the content, it's the analysis required and the high level of literacy. Politics and Economics aren't exactly easy either!
Those are good choices and I don't know who has claimed that they are "easy", but that person is very mistaken.
