Information for heads of centre, heads of department
As part of their overall quality assurance, centres should consider the grades for this year’s cohort compared to cohorts from recent years when exams have taken place (2017, 2018 or 2025) at
Grading systems by country
Scores of 91–100% are considered excellent, 75–90% considered very good, 55–64% considered good, 45–55% considered fair, 41–44% considered pass, and 0–40% considered fail. A percentage above 65% is referred to as the 1st Division and indicates a high intellectual level.

Grade 1 through 2.5 embryos seem to have the greatest potential for developing to the blastocyst stage. However, a grade 3 embryo may also be of good quality if its appearance can be explained by asynchronous cell division rather than by poor development.

In general, many cleavage stage embryos receive their grade based on the amount of fragmentation: Good: 25% fragmentation Cell symmetry (cell size) Ideally when a cell divides they should both be the same size.
What is GRADE? | BMJ Best Practice
GRADE has four levels of evidence – also known as certainty in evidence or quality of evidence: very low, low, moderate, and high (Table 1). Evidence from randomised controlled trials starts at high quality and, because of residual confounding, evidence that includes observational data starts at low quality.
- What are the advantages of DOP chemical?
- It has good comprehensive performance, good mixing performance, high plasticizing efficiency, low volatility, good low temperature flexibility, water extraction resistance, high electrical performance, good heat resistance and weather resistance. DOP chemical is a general-purpose plasticizer.
- What is medical grade dioctyl phthalate DOP?
- Medical-grade dioctyl phthalate DOP. Mainly used in the production of medical and health products, such as disposable medical appliances and medical packaging materials. High plasticizing efficiency, fusion rate. Good low volatility, UV-resisting property, water-extracting proof, cold-resisting property.
- What is DOP used for?
- In addition, DOP is also used as a condensing agent, a friction reducer, an organic solvent, and a gas chromatography stationary liquid. Electrical dioctyl phthalate DOP. In addition to all the properties of general-purpose DOP, it also has good electrical insulation properties, and is mainly used to produce wires and electricity.
- What is DOP plasticizer?
- DOP plasticizer is a transparent oily liquid with no visible impurities in appearance, which is insoluble in water, soluble in most organic solvents such as ethanol, ether, mineral oil, etc. As the most widely used plasticizer in industry, DOP as good compatibility with most synthetic resins and rubbers used in industry.
