T test, chi square value problem

Was practicing questions on the CFA study website, im using Kaplan materials. However some of the questions for t test and chi square requires values for df 220 or some other odd numbers that isn’t provided in the tables. Any idea where can I find these odd values as I cant do the questions without it

You can interpolate / extrapolate linearly to get approximations.

You won’t need to do that on the real exam.

The values above 200 should be pretty close to the ones that are tied to 200, so just use the values for 200. The marginal differences become infintesimal.
