Which is best for Engineering Degree 3 A levels or 4?

[S0upVat]

Ds def doing Maths,Further Maths and Physics. He’s toying with chemistry too. He’s bright and should get 8/9s in these subjects but a tad fly by the seat of his pants, leave it all until the last minute ie not a swot. Would it be better to focus on 3 to get more chance of As? Ie are 3 strong better than 4 weaker? He’s supposed to do a project if not doing a 4th. Any ideas of something that would help with Engineering applications?

AS are worth nothing now

The bit of paper may not be 'worth' much - but studying an extra subject for a year isn't worthless!

I agree Errol, particularly if it is some relevant - in the case of engineering, either further maths or chemistry (whichever isn’t taken to the full A level).
