To enter into the legal profession (i.e. become a lawyer - solicitor or barrister), you will more often than not need to take a Law degree at university (degree) level. The most common degree is the Law LLB 3-year course, which requires no certain A-levels. Helpful A-levels to do would include Law (of course), Sociology, Politics and English, among others. Top law firms will look back at your A-levels to help them decide whether or not to employ you, so they do matter to a certain extent.
The long and short of it is that you can do any A-levels to get onto most university courses, but obviously if you've done, for instance, Photography, Media and Music, you are less likely to. Law gives you some excellent background knowledge and a great taste of what's coming, but everything you learn is re-covered in university.
Personally, I studied Law, Psychology, Sociology and English Language/Literature at A-level, and I felt that Sociology in particular was very helpful; English also greatly helps with your writing ability, crucial for completion of a Law degree.
Conclusion - you can study any A-levels, as it's the degree that counts! You can even do a non-Law degree, but it means you'll have to study further courses... feel free to email me at email@example.com for more info!
The money that his Mom is receiving is social security money that is supposed to be used to support her late husbands child until he turns 18 or 21 depending on if he goes to college or not. It is not issued to spend on drugs or alcohol or to buy gifts for her boyfriend. If you feel she is abusing it you should call the social security administration or contact them online and file a complaint. The more information you have the more likely it will be for them to investigate her. You'll need his fathers name because they issue it off his social in her name for the benefit of their child together. I know this cause my first husband passed and I receive benefits for my 7 year old. I use it to pay for his school costs, uniforms, school lunches, etc. Whatever I have left over goes into a savings accounnt for him.
