I have been getting about 60% of questions right on the medentry and acer exams. I really dont know if thats a good score for the umat. Any ex umatters out there who could share their knowledge and wisdom? Please and thank you!

Yeah I've been getting 60-70% of the questions correct on Medentry exam papers too (and absolutely atrocious MedEntry percentiles). I think that given that MedEntry is repution-wise, more difficult than the actual UMAT to some extent, it isn't a too-bad score, but definitely not superb. I think between now and Wednesday, it's important to read through the worked solutions, and in doing that, basically look at things you've done wrong, and how you can avoid such things on the day of the actual UMAT.
What are these 'bucketful of strategies' you speak of
By reading through worked solutions, looking at things you've done wrong and keeping these at the back of your mind while doing questions in the UMAT, you're taking strategies into the exam. I've been doing terribly at the Medentry practice papers, but I'm not so much worried about my marks - instead, I'm focussing more on things I've done wrong and how I can rectify these, leading up to the UMAT.
Positivity is also important - if you're going to sit there saying, 'I'm going to fail', you'll approach the test with pessimism and this is really likely to stress you out and hinder your ability to do well. So, remain positive, cool, calm and collected, and also be excited about doing it (as insanely difficult as that sounds), because being enthusiatic means you're more likely to engage with the material and thus decipher the answers with more accuracy.
