I have completed the OG Book practice test (both), PP1 (free), and PPP+1 (paid). I have 2 more weeks until my exam and want to 1 more practice test? Which will be the best to give most realistic to actual exam? Hearing mixed things about PPP+ are similar to exam or actually harder, and the free ones are too easy. Thoughts? Hoping to boost confidence over the next 2 weeks while also getting accurate score results 
TY!
PPP+ test level is really at par with what you will find on real GRE. If you are done with PPP+ and still want to give a practice test you can give the manhattan test series which has 7 sets.
All the best! and keep giving practice tests, it really helps
