Everyone recommended different resources and I kept switching between them. Questions from other students often helped me as well. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.
Juliette Guillon
I was doing questions for ACT Reading on my own but never had a steady routine. I finally understood what was going wrong in ACT Reading. My tutor usually asked me to explain my thinking before stepping in. My written answers became shorter, clearer and easier to follow. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)
Femke Hartmann
Breaking Time Management into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.
