Practical plus real-time questions

More than 70 practice questions i got with the premium membership. I was under the impression that this is going to take me entire two months to complete but when i started giving mock tests based on the SRE Practitioner certification exam that these tests are timed and i will have to increase my speed. Gradually i started completing all the mock tests without any time limit. This structured my preparation for the exam. I have pass actual exam!
