What is the grade-prediction course?
In short: A course for collectors on measuring centering and assessing surfaces, corners and edges under magnification, the same way a pre-grade assessment does.
The course teaches you to read a card before you pay to have it graded: how to measure centering, how to look at a surface under raking light, and what to check on corners and edges.
It teaches a method, not a promise. No course or assessment can tell you what a grading company will decide; see will my card grade a 10?. It is self-paced and priced per seat, quoted in writing.
It is written for collectors who decide for themselves what to send, and it covers the same things a pre-grade assessment looks at: centering, surface, corners and edges, each written down as observed. By the end you can sort a stack into cards worth a closer look and cards that are not, before you pay any grading fees.
If you want a second pair of eyes on specific cards, a consultation can be added to the course, or you can book a pre-grade assessment for the cards that matter most. See is my card worth grading?
