In this paper, we investigate the exponent of convergence of $f^{\left(i\right) }-\varphi$ where $f\not\equiv 0$ is a solution to certain class of linear differential equations with analytic and meromorphic coefficients in the closed complex plane except a finite singular point and $\varphi$ is a small function of $f$ .
