Appreciate some views or help about my boy's uni application.

He's gotten these A-levels results: General Paper:A, Physics:A, Chemistry:A, Maths:B & Economics:D. We are are planning to apply for Unis around the London area or anywhere within 2 hour car ride from Heathrow. He's thinking along the lines of Engineering (probably EE or Mechanical).

What would you guys recommend putting into his UCAS application? Realistically, what's the best Uni he can shoot for, and what's a good insurance Uni for him?

Thanks for any comments you may have.
