Slightly different reply but I would suggest not working on engineering and having some sort of adventure. You will have worked very hard to get your A levels, you will have 3, 4 or even 5 years of hard academic work before entering the world of work. Get a backpack, book a one way train to Europe and don't come back until for at least a couple of weeks. It will be a great experience and you won't have many opportunities to do similar things with the same level of freedom again.
