Documented online IB result, May 2025: a final 7 in Physics SL and a 6 in Math AI HL
Blake Eustaquio worked online with Renzo Diaz from September 2023 to May 2025 while attending the Metropolitan School of Panama. His reported starting grades were 3 in IB Physics SL and 4 in IB Math AI HL. His final May 2025 grades were 7 in Physics SL and 6 in Math AI HL. Predicted grades were 7 in both subjects; the distinction between predicted and final results was clarified in a private written confirmation in September 2026.

The record
What the record shows
| Course | Reported starting grade | Predicted grade | Final grade, May 2025 |
|---|---|---|---|
| IB Physics SL | 3 | 7 | 7 |
| IB Mathematics: Applications and Interpretation HL | 4 | 7 | 6 |
Where the numbers come from: the starting grades are Blake’s own words in his public review (he confirmed in writing that the 3 was Physics); the predicted and final grades come from his written confirmation, held on file. The table is Renzo’s record of those sources.

Two courses
Physics SL and Math AI HL
Physics SL: a 3 on his first report card, a final 7 in May 2025
May 2025 was the first examination session of the new IB Physics guide: five themes, a Paper 1 in two parts and no past papers in the new format yet. From September 2023 the weekly sessions worked from that current guide, paper by paper: problems from school first, then the syllabus ahead, then practice questions on whatever he had got wrong.
Math AI HL: a 4 on his first report card, a final 6 in May 2025
He took Mathematics: Applications and Interpretation at Higher Level alongside Physics. His school predicted a 7 and his final grade was a 6. The weekly pattern he describes in his review covered both subjects.

His review, in full
“I cannot recommend working with Renzo enough. When I first started working with Renzo in the first year of my IB journey, I was struggling a lot with Physics and Math Applications (where my first report card scored 3 & 4). Also, at this time the IB changed the syllabus and created new papers making class in school a blind test. Despite this difficulty, Renzo adapted fully and helped me bring both classes from low grades up to 7's. Apart from being a very kind and intelligent person, Renzo has the resources (such as revision village, Showbie, and books in pdf format to guide the student along). Renzo adapts his teaching to the students needs, he can spend more or less time on a subject as long as the student understands it. In my case, Renzo and I had a set schedule per week, where we would work on problems I needed help with from school and advance in covering IB syllabus content. Then, he would send me practice questions to do on Revision Village and Showbie to go over my incorrect answers in the following session. Overall, if you are looking for someone who cares about your success, knows IB or IGCSE content by heart, and can break down difficult content into something much more understandable, Renzo is definitely worth it!”
Editorial noteThe 7s in his review are his predicted grades. His final IB grades, May 2025: 7 in Physics SL, 6 in Math AI HL.
