Day before results day and my son seems to be very anxious and nervous about the whole thing. Just for some context, he got into Cambridge for Engineering but now after taking more courses, going to lectures and work experiences he's unsure of this decision. He says he wants to change to either Physics or Computing, but for one thing can't choose which one and for another doesn't think they'll let him switch. He also doesn't want to take a gap year and reapply as he is unsure if he'll get in again and doesn't want to spend a year out of education.
This has been going on for quite some time now and I've tried to help him but it's gotten worse over time. I don't really know how to help him decide as it has been so long and he has tried a lot to make a decision and still can't. He initially wanted to apply for Physics (I believe he is most passionate about this) but changed because of the apparent better opportunities and salary. I hate seeing him so stressed as he used to be so happy and curious, but I'm not really sure how to help him.
