  6. text nyo na lang ako kung oorder kayo ng reviewers for major or for gen ed and prof ed. sa 0999-9401794. Pede rin pm me sa messenger ko sa fb ko: crisencio m. paner. I assure you very effective mga reviewers ko, napakarami ng nakapasa dahil dito. Da best din nyong gawin ay magpa let coaching sa akin, lalo na kung ilang beses ka ng bumabagsak sa let.
