  We express all the newforms of weight $2$ and levels $30$, $33$, $35$, $38$,
$40$, $42$, $44$, $45$ as linear combinations of eta quotients and Eisenstein
series, and list their corresponding strong Weil curves.
  Let $p$ denote a prime and $E (\zz_p)$ denote the the group of algebraic
points of an elliptic curve $E$ over $\zz_p$. We give a generating function for
the order of $E (\zz_p)$ for certain strong Weil curves in terms of eta
quotients and Eisenstein series. We then use our generating functions to deduce
congruence relations for the order of $E (\zz_p)$ for those strong Weil curves.
