Hi, a warm welcome to the site. If a unit has gaps it'll be returned to you so you will know if they are correct or need expanding.
Check what dates and deadlines your course provider's given you so you can plan ahead for study time, organising your evidence and your assessors visits to the setting, use a separate calendar to mark out your schedule if necessary xx
Enlist the help and support of colleagues in your workplace so you feel a little less alone and check you have copies of all the setting's policies and procedures and a
handbook to guide your research - link is to the work based learner edition on amazon.co.uk
To research safeguarding you'll need to know the laws, regulation and guidance, what it says in your early years framework (if you work in England this will be EYFS) what your setting's safeguarding policy states and know your job description or role and responsibilities within the setting.
Hth best wishes
