After my first attempt, I wanted a calmer and more focused plan for the retake. The group never had more than six students, so it was easy to stay involved. I stopped choosing answers by feel and started looking for evidence in the passage. Going back to the lesson recordings helped when I forgot a small step. Questions from other students often helped me as well. It was an intense period, but it was worth it.
Marine Roussel
After my first attempt, I wanted a calmer and more focused plan for the retake. Having the lesson move at my pace made the process feel much easier. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.
Sophie Gallagher
I had been studying alone, but my results stopped improving after a point. Choosing questions by topic made my practice time much more useful. I started seeing shorter solutions that were easier to check under time pressure. Going back to the lesson recordings helped when I forgot a small step. After enough examples of the same question type, the repeated mistakes decreased. Thanks to TestPrep for helping me stay on track.
Hayden Lambert
I came back to Verbal Reasoning after a long break and wasn't sure where to begin. Thanks to TestPrep for helping me stay on track.
Matilda Aldridge
The feedback I received on Analytical Writing was clear and practical. I went into the exam much calmer than I would have before.
Alper Gokce
Over time, Data Analysis became one of the most organized parts of my GRE General preparation. I started noticing the reason for a mistake much faster.
Connor Brennan
Balancing GRE General preparation with university and work was harder than I expected. We didn't spend extra time on things I already knew. We focused more on understanding what the problem asked than memorizing formulas. I never felt awkward asking the same thing again. My tutor could see my reasoning and usually found the source of an error quickly. The preparation felt calmer than I expected.
Thomas Baxter
I finally understood what was going wrong in Sentence Equivalence. I stopped choosing answers by feel and started looking for evidence in the passage. My preparation became much more regular and easier to track.
Anders Mazur
I had been studying alone, but my results stopped improving after a point. Working across different difficulty levels made new questions feel less surprising. After a while, the questions started to feel much more familiar. Thanks to everyone who supported me.
Erik Stanic
I had collected too many resources without knowing when to use any of them. The feedback I received on Verbal Reasoning was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. A lot of my mistakes came from rushing through the wording of the question. I went into the exam much calmer than I would have before. A big thank you to my tutor for all the support :)
Shanshan Guo
I knew my target, but I didn't have a realistic routine for GRE General. Thank you to the tutor who stayed supportive until the end.
Lalita Lertchai
After my first attempt, I wanted a calmer and more focused plan for the retake. Near the exam, it was clear what to keep doing and what to stop. Full-length mocks helped me get used to the real exam pace. I started seeing shorter solutions that were easier to check under time pressure. My confidence improved along with the results. Thanks to everyone who supported me.
Hugo Lambert
In Text Completion, timing was costing me more points than the content itself. The plan changed with my mock and homework results, so the work never felt random. My tutor could see my reasoning and usually found the source of an error quickly. My written answers became shorter, clearer and easier to follow. I found a better balance between regular school and exam preparation. Thanks to everyone who supported me.
Lan Do
I had collected too many resources without knowing when to use any of them. One bad mock no longer made me want to drop the whole plan. Discussing why the other choices were wrong helped more than I expected. I'm glad I worked with my tutor through this process.
Duy Le
I had collected too many resources without knowing when to use any of them. I became much more comfortable asking questions in class.

Paige Prescott
After my first attempt, I wanted a calmer and more focused plan for the retake. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. The preparation felt calmer than I expected.
Junseo Sung
Balancing GRE General preparation with university and work was harder than I expected. Over time, Sentence Equivalence became one of the most organized parts of my GRE General preparation.

Thanks to everyone who supported me.
Zeynep Sari
Balancing GRE General preparation with university and work was harder than I expected. A clear plan for the final weeks made priorities much easier to see. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.
Matilda Gilmour
After my first attempt, I wanted a calmer and more focused plan for the retake. My tutor could see my reasoning and usually found the source of an error quickly.

Thank you to my tutor and the TestPrep team.
