I empathized with your concern as a parent of a GEPer. Now, my kid has long graduated from GEP and is a young adult awaiting uni. But your kid’s experience somewhat mirrored his. He was also not top 3 in his pri sch prior to GEP but did well enough to get invited on stage for some prize presentations. HCL was his only Achilles’ heel; he was comfortably proficient with the other 3 subjects.
So imagine my shock when he came back with his first term GEP Eng test paper and got 23 marks. Now that I looked back, it was quite funny coz upon seeing that figure, I did a quick mental calculation and my initial impression was that it was 70+% and consoled myself that although that reflected a drop, it wasn’t too bad in the grand scheme of things. Later my kid corrected me that it was upon 40, not 30. That represented a drop of more than 30% from P3 to P4! His Eng basically fell off the cliff. My jaw dropped (but I was careful not show it in front of him).
I don’t have all the inputs to your qns but will share some observations that I think are relevant. I feel that the GE selection is by and large accurate as I’ve the benefit of witnessing the progression of some of my kid’s frens, from P4 all the way to A Level. Vast majority (easily > 90%) of them aced PSLE and latter on, A Level. That trend of being academically excellent was unerringly consistent.
With regards to the issue of others prepping themselves for GE selection, I feel that you don’t need to bother yourself with it. Why concern yourself with what others do? With the removal of GEP DSA, it sharpened the focus back to true learning and reduced the pressure to be competitive with other batch mates.
Last of all, you do have the prerogative to remove your kid from the program. However, if I were you, that’s the last thing I’ll do. The reason is this - I don’t want my actions in any way to condition my kid to think that whenever he hits a roadblock, he seeks avoidance and simply capitulates. I think that’s extremely damaging to a kid’s psyche in the long run. I can lower my expectation but he should go thru challenges, as long as his mental health is not affected.
It is early days yet and rereading your post, I perceived that you’re more stressed than your kid while he seems to be enjoying the journey so far. One suggestion you could try is to discuss this issue with him (on the possible reasons for his GEP Sci tr’s comments) and find ways mutually agreeable on the best approach forward to improve the situation. Your kid sounds like a bright child and I suspect that you don’t even need to provide any solutions for him. Just ask the right qns and he’ll be able to come up with the ans himself.
One thing I aware is that it is not easy to give constructive feedback and very often, the provider does it with good intentions. So give the tr the benefit of the doubt for the moment.
Good luck.
