The ArchLDS Part 1The ArchLDS Part 1LDS Part 1 preparation
Built for dentists sitting the Licence in Dental Surgery Part 1, the written stage of the Royal College of Surgeons of England route. You should not have to buy four books and stitch them together yourself.
Passing the LDS is not about memorising thousands of pages. It is about knowing the right information, understanding how to apply it, and being able to recall it under exam pressure.
This series was built with one objective: the most focused, structured and exam-oriented preparation available for the Licence in Dental Surgery, Part 1. Every section is organised to help you revise efficiently, sharpen your clinical reasoning and actually retain what you learn — whether you are starting months out or reviewing in the last few days.
Three hours free — 250 questions from the question bank, each with its explanation, and the first card of every revision subject in full, with the heading and summary of every other card. We email you a link; clicking it starts the clock, so ask for it when you have a clear run.
One free trial per email address. No card, nothing to cancel.

Your course
Choose where you want to work today. Your progress is saved as you go.
Every question has been verified and has a full explanation. The bank is split into Essential and Important questions.
For example: a question asks about the parotid (Stensen’s) duct. Its explanation also covers Wharton’s and Bartholin’s ducts. So a question on Wharton’s duct sits in Important, not Essential: you have already met that concept. Your time goes on new concepts, not ones you have already studied.
Every subject is set out in topics, with the important points structured and summarised. Start a subject and finish all of its topics. We recommend starting with your weakest subjects, and doing their Essential questions alongside.
Once you have built up your knowledge and done a good number of Essential questions, move on to the UK guidelines and BDA sheets, and aim to finish them in about two weeks. This is where candidates lose a lot of marks.
When your exam is booked, send your booking confirmation to our admin team on WhatsApp. We then open the two-week final revision, 72 hours before the exam and the feedback structured exam mocks for you: full papers set out by exam sitting, from 2023 to 2026. The sections are named for two weeks and 72 hours, but some candidates need longer, especially if they have not been through the revision guide properly, so start them early.
If you would rather not work through the full revision guide, this is the order we recommend:
