Ailda is great. She knows any material or can figure it out quickly and explain concepts and easily translates algebraic equations into Excel. She's patient, with an easy-going style and a smooth formality. Time goes by so fast its incredible (and disturbing haha). Scheduling needs to be around a M-F 9-5 job, is the only limitation. If I cast aside my selfish desire to monopolize her available time.... then I can Highly recommend!
