This page has links to UK A Level past papers and solutions. The past papers are currently for the legacy specification examined for the last time in Summer 2018. There is of course much material here relevant for the new specification. (See Mapping Documents.)STEP and Oxford Admissions test links are at the end of the post.
From crashMATHS, note the A Level Practice Papers and mark schemes, this looks like a very valuable resource. There are several papers and mark schemes available with more coming. Versions are provided for AQA and Edexcel, these use the style of papers we see from the exam boards. Currently, there is nothing for OCR. ForMathematics the content is the same for all the boards and for Further Mathematics we have a prescribed core that must comprise approximately 50% of its content. This common content as we have with GCSE is very useful indeed as we can use resources from all the examination boards.
I do like the way the pure section of the worksheets includes a mix of basic, problem and modelling questions.
Exam Solutionshas thousands of worked video solutions to A Level questions. Note the tabs at the top of the site, select A-Level Maths and then your chosen exam board. Exam Solutions has updates on the new A Level specifications.
For some excellent PowerPoint resources with A Level questions and mark schemes by topic try Mr Westwater’s resources on TES. (Twitter @westiesworkshop). Though Edexcel questions these are clearly useful for other examination boards also. There are six of these PowerPoint files available:
See also MadAsMaths for a brilliant collection of questions at various difficulty levels.

From Underground Maths, to challenge students I find the Review Questions excellent, so many excellent questions from old A Level papers clearly organised and with very full solutions. Note the Mapping Document (scroll down) for the new A Level specification with suggested resources.

For an extensive collection of Challenging questions for Advanced Level students we can turn to the Oxford Maths Admissions Test, note the menu on the right-hand side of the page, many papers and also solutions are available. For more Oxford MAT questions see this extensive collection on Underground Mathematics. These Underground Mathematics resources will provide so much more than the question in each case. Note the suggestions and solutions.
