# Problem with \part (Numbering, partend,

my code is like this:

``````\input{sections/Preface}\clearpage
\part{Problems}
\input{sections/Text1}\clearpage
\input{sections/Text2}\clearpage
\part{solutions}
\input{sections/sol1}\clearpage
\input{sections/sol2}\clearpage
\input{sections/sol3}\clearpage
\input{sections/sol4}\clearpage
\input{sections/Closingword}\clearpage
``````

The things I would like to change:

• Remove Numbering from Preface (Using section* in the file makes it disappear from the table of contents)
• Restart Numbering whenever a new part starts (So Sol1 is numbered as #1 and not #3)
• Remove numbering from the closingword and make it not included in the second part
• On the PDF itself, Problems is written twice and I only want it one time there (Twice makes no sense to me and I don't know how to change it)

P.S. I'm not allowed to use any other documentclass as I'm given

If you use \section* and you want it to appear to the table of contents, you can use the \addcontentsline command. Something like this:

``````\section*{Section 1}
``````\setcounter{section}{0}
