Contract law

Unpaid order – please place your bids Dear Sir or Madam, I have an online exam therefore, there are 4 questions that should be done. Moreover, two of them are essay type question while other two are problem questions. I attached some past exam papers and reports so you can be more clear about how it`s gonna be. I need around 900 words per question. It should be noted that this is English contract law so I need someone who has knowledge about English contract law. Furthermore, I attached some materials that I learn so please read the main chapters and subchapters just to expect what you are going to be asked about and please try to stay within that module guide. Lastly, I need around 50-60% to be the grade so I am not looking for first upper grade. Thank you, Best,
