Just to add a bit more as a first year Apprentice.
You will be placed on the Trailblazer course, which isn't specific to Jaguar Land Rover (JLR), however it is the apprenticeship scheme you will follow that many other large companies also now do. I think it's only up to third years that have done this scheme, whereas years four and five (no sixth years yet) do a different scheme.
Your at college full time for the first year and then do one day a week at college for the second year, followed by the rest of the apprenticeship block release at Warwick Uni.
You will only do modules relevant to your job role at college, however will get a very basic understanding of everything. For example the Electrical guys are the only ones that do Electronic and Electrical Principles (EEP) (so actual theory behind the electrical stuff rather than just electrons flow around a circuit, you need a ground etc.). This additional module is relevant as it goes towards your foundation degree, as well as the pathway you will be placed on at Uni.
Everyone does CATIA for CAD, which is what is used in plant and is the business version of Solidworks, almost identical just everything is renamed so expect to learn it all again like I did if you were proficient in Solidworks. If your in Body CAD or any of the other CAD departments, similar to EEP for electrical pathway you will go more in depth and do an actual module and be assessed on your CAD work.
Another example is the Manufacturing Processes Unit, only completed by the guys on the manufacturing pathway. You will get a very basic understanding of this in the Materials Unit, so you will not miss out but to a lot of us it's not relevant so we don't need to do it in much depth anyway.
If you have done A Levels you will be covering a lot of the same material therefore it's not particularly hard and there's plenty of time to do any assignments and revision for Phase Tests you may have.
About the pay your final six months in the last year will be the advertised 36.5K, however the Apprenticeship contract is for 6 years but after completion you must work for the company for another three (I believe they only started doing this from this year), Due to this you are only on apprenticeship salary for six years which caps at the 36.5K. After that contract expires you are moved to an engineers contract with an engineers salary, which is 40K+, higher if you become project lead or even higher for management.
I've got no intentions to leave so can't comment on other opportunities, my department is mainly made up from apprentices, so everyone can teach one another. Saying that everyone else is more than friendly enough if you need any assistance, and you can normally have your LL6 (so your manager) and then your LL5 (your managers manager) sitting only a few seats away from you so it's not like your never far away from someone that has a real understanding of their work. (LL1 being CEO).
You will have to pay any tuition fees the company paid out for if you do decide to leave so it's not a case of get up and clear off when you want you really are locked in for six years. After the six years you no longer need to repay but as stipulated in the contract you must work for three further years otherwise you'd be in breach of the agreement.
Just about the specialising, your locked to your department for the apprenticeship contract length, however when you switch over to your engineers contract you have the option to move where you want, you just need to remain working with the company to satisfy the further three years. While your on the apprenticeship contract you can get placements in other departments in your area, so if you're in Powertrain and your placed in the NVH department, you can get a placement in the engine components department.
All I've said here is what I've experienced and been told by people in my department and managers, and a lot of changes have been made this year so it could be different from Tubbz's information as well as what you'd experience next year. (For example a lot of workshop modules have been cut, with the only ones mandatory being milling, turning, fitting and welding. Depending on your pathway you may do one or two more like engine tear down or electrical wiring).
Sorry about grammar and spelling done on phone.
