Other threads are titled "A-level subjects advice needed" or similar, rather than something vague. You also put posted your primary school query in the part time jobs thread, so people who are interested/experienced in the area of primary education and qualifying for that looking are unlikely to be looking in that forum.
It's important to select the correct forum to post your thread in, and then choose and informative and inviting thread title. Both of these will go a long way to getting you answers. Additionally, your recent threads with no responses have been active for less than a day, and you posted in the middle of a work/school day. Most people are more active in the evening.
I have now requested your primary education thread to be moved to the relevant forum and tagged in someone with some knowledge of the area. Regarding A-level choices, people can't just pull suggestions out of a hat - without any indication of your background (such as which subjects you did in GCSE, how well you did in them, how much you enjoyed them, how your enjoyment compared to your performance etc) it's almost impossible to make a suggestion. I can certainly suggest many sets of A-levels however they may be well be irrelevant, undesirable, or unfeasible for you...
