I took the ASTB once and got a 46, 5, 5, 6, 44 (not good enough) and I am studying to take it again. I find myself strugging with the OAR portions due to the time restraints. Does anyone know how the algorithm on the OAR actually works? Like what determines if you get less or more questons? I have been studing the math with 1 minute and 20sec per problem and struggling a lot to keep up. Is this a realistic pace or will I have longer on the actual exam depending on how I do.
