Im on an book report class document and I want a extremely large \mathscr{T} covering a considerable portion of a page. I know how to do this without the \mathscr font but as soon as I add the font, the size of the letter is reduced. How can I achive a humongous \mathscr{T}?

It would have saved time if you would have provided an MWE (I had to reverse-engineer that you probably use the mathrsfs package).
\documentclass{article} \usepackage{graphicx} \usepackage{showframe} \usepackage{mathrsfs} \begin{document} \resizebox{!}{0.9\textwidth}{$\mathscr{T}$} \end{document}

If you use Unicode fonts, you can use the Scale= option (here, 40, arbitrarily).
It would more practical to set it as an ornament letter, though, rather than as part of an actual equation.
MWE
\documentclass{article} \usepackage{xcolor} \usepackage{unicode-math} \setmathfont{TexGyrePagella-Math} \newfontface\fscr{TexGyreSchola-Math}[Colour=red,Scale=40] \newcommand\fscrT{{\fscr 𝒯}} \usepackage{showframe} \begin{document} \fscrT\kern-20em\llap{$x^2+y^2=z^2$} \end{document} 
The .fd file for rsfs has only fixed sizes, as was normal in olden times:
\DeclareFontFamily{U}{rsfs}{\skewchar\font127 } \DeclareFontShape{U}{rsfs}{m}{n}{% <5> <6> rsfs5 <7> rsfs7 <8> <9> <10> <10.95> <12> <14.4> <17.28> <20.74> <24.88> rsfs10 }{} Nowadays, the font is available in Type1 format, so arbitrarily scalable.
\documentclass{article} \usepackage{showframe} \DeclareFontFamily{U}{rsfs}{\skewchar\font127 } \DeclareFontShape{U}{rsfs}{m}{n}{% <-6.5> rsfs5 <6.5-8.5> rsfs7 <8.5-> rsfs10 }{} \begin{document} \begin{center} \fontsize{256}{0}\usefont{U}{rsfs}{m}{n}T \end{center} \end{document} 
You can add kerning in order to cope with the fact that the character extends beyond its bounding box on the right.
\resizebox{!}{0.9\textheight}{\Huge L})
