练习表间距均匀

Question

我想设计一张练习表。以下是我目前所得到的：

\documentclass[DIV=15]{scrartcl}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[english]{babel}
\usepackage{microtype}
\usepackage{amsmath}
\usepackage{mathrsfs}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{csquotes}
%\usepackage{dsfont}
\usepackage{lipsum}
\usepackage{enumitem}

\newcommand{\points}[1]{{\small\textbf{(#1)}}}

\newcounter{ExCount}

\newenvironment{exercise}
[2]
{\refstepcounter{ExCount}\par\medskip\noindent\textbf{Exercise \arabic{ExCount}%
        \ifstrempty{#1}{}{~\normalfont(#1)}} \hfill{\small (Points: \textbf{#2})}%
    \hrule\vspace{\itemsep}\noindent\newline}
{\par\medskip}

\newlist{exlist}{enumerate}{2}
\setlist[exlist,1]{label=\roman*)}
\setlist[exlist,2]{label=\alph*)}

\newcommand*\raiseup[1]{%
    \begingroup
    \setbox0\hbox{\tiny\strut #1}%
    \leavevmode
    \raise\dimexpr \ht\strutbox - \ht0\box0
    \endgroup
}

\begin{document}
    \begin{center}
        Some Course (2019) \hfill
        Prof. xyz $\cdot$ xyz
        \hrule

        \vspace{0.2cm}
        {\large \textbf{Exercise 01} } \hfill \raiseup{\small Total points: \textbf{4 points + 4 extra points*}}

        \vspace{0.1cm}
        \small\raggedright (Deadline: 20/04/2019)
    \end{center}

    %%%%%
    %
    % Some Topic
    %
    %%%%%
    \begin{exercise}{Some Topic}{10}
        \lipsum[1]
    \end{exercise}

    %%%%%
    %
    % Some Other Topic
    %
    %%%%%
    \begin{exercise}{Some Other Topic}{8}
        \begin{exlist}
            \item This is some exercise about weird math stuff.
            \item This is another exercise about more weird math stuff.
            \begin{exlist}
                \item This is some exercise about weird math stuff.
                \item This is another exercise about more weird math stuff.
            \end{exlist}
        \end{exlist}
    \end{exercise}

    %%%%%
    %
    % More Topics
    %
    %%%%%
    \begin{exercise}{More Topics}{8}
        Let something be something. Then:
        \begin{exlist}
            \item This is some exercise about weird math stuff.
            \item This is another exercise about more weird math stuff.
            \begin{exlist}
                \item This is some exercise about weird math stuff.
                \item This is another exercise about more weird math stuff.
            \end{exlist}
        \end{exlist}
    \end{exercise}

    \hrule
    \vspace{\baselineskip}
    \centering
    Good luck! :)
\end{document}

但是现在，列表会导致不理想的间距。我希望间距在任何地方都相同（尤其是列表前后，就像没有间距一样）。你知道该如何解决吗？

此外，您还有什么改进建议吗？
