Yes you are right there are cross overs. And many clever students become complacent and cruise, my DS is one of them. But the clever ones do not need to work flat out for 3 years to maintain the grades.
Education is just much easier if you are naturally clever. Concepts are easier to understand, memorising facts without being able to apply them can be frustrating. Higher education is all about analysis, application and critical thinking.
In research we make no advancement in sticking to the facts, questioning current and historical thinking is how we move forward. Also it is really important to see failure as a learning experience. So many instance of disappointment on TicTok, A level students who think that they deserve an A* or A. Lots of parents and students looking for remarks even though they have got into their firm choice.
I have 3A levels and an S level ( prize for any one who knows what that one is, I didn’t and I took one) in 42yrs no one has asked me what Alevel grades I achieved.
And in 20yrs from now no one will be asking this year’s A level students what grades they achieved. They are just the currency we use to move on to the next level.
I recently read a very sad Twitter post from a new graduate who was disappointed that she was only awarded a 2.1 despite achieving 3A*s at A level but of course that was 2020 when they were giving them away in cereal packets. The system failed this cohort as it has done the last 3 yrs and this year as well.
Because of their inflated grades they are under the impression that they will continue to be top of the class.
As I said, it is 42 yrs since I did A levels. While helping my DS revise last year I was confused by how much time they spend on how to make the most of marking schemes. Passing an A level seems to be more dependent on knowing you way round marking schemes than actual knowledge of a subject. So memorising blocks of information to slot into the marking scheme is definitely an advantage.
