You can find some (theoretically) helpful comments from me and others in this older thread about historiography-based essays. A couple of notes though:

1. No one here is really able to give you all the information you need here - the only person who can give you authoritative insight into what the marker expects is the person marking it. If you're having trouble, ask them for guidance - while they may be limited in the amount of help they can give, they should be willing to answer questions about the approach you take.
2. It's also tricky to answer your question because it's not clear how you would structure a 'normal history essay'. Speaking as someone who has marked their fair share of first-year history essays, there's a pretty broad spectrum of ways students structure their essays, and a lot of common approaches are not what I would consider ideal. BUT I would say that in terms of the way I think about essay writing, there is more similarity than differences, in that in both cases the structure revolves around the central argument you are trying to make - your structure is your roadmap for covering the ground you need to in order to convince the reader of your specific central claim. The main difference is then in the nature of the argument and evidence rather than how you think about the structure.

Hi - we as mods have approved this thread, because while this is a homework question, it is asking for clarification or resources, rather than the answer itself, which is fine according to our rules. This policy is further explained in this Rules Roundtable thread and this META Thread.

As a result, we'd also like to remind potential answerers to follow our rules on homework - please make sure that your answers focus appropriately on clarifications and detailing the resources that OP could be using.

Additionally, while users may be able to help you out with specifics relating to your question, we also have plenty of information on /r/AskHistorians on how to find and understand good sources in general. For instance, please check out our six-part series, "Finding and Understanding Sources", which has a wealth of information that may be useful for finding and understanding information for your essay.
