In this study, a Galerkin-like approach is applied to numerically solve high-order integro-differential equations having weakly singular kernel. The method includes taking inner product of a set of monomials with a vector obtained from the equation in question. The resulting linear system is then solved, yielding a polynomial as the approximate solution. Additionally, the technique of residual correction, which aims to increase the accuracy of the approximate solution, is discussed briefly. Lastly, the method and the residual correction technique are illustrated with several examples. The results are also compared with numerous existing methods from the literature.
