  We test the predictions of the L-functions Ratios Conjecture for the family
of cuspidal newforms of weight k and level N, with either k fixed and N --> oo
through the primes or N=1 and k --> oo. We study the main and lower order terms
in the 1-level density. We provide evidence for the Ratios Conjecture by
computing and confirming its predictions up to a power savings in the family's
cardinality, at least for test functions whose Fourier transforms are supported
in (-2, 2). We do this both for the weighted and unweighted 1-level density
(where in the weighted case we use the Petersson weights), thus showing that
either formulation may be used. These two 1-level densities differ by a term of
size 1 / log(k^2 N). Finally, we show that there is another way of extending
the sums arising in the Ratios Conjecture, leading to a different answer
(although the answer is such a lower order term that it is hopeless to observe
which is correct).
