Talk to your principal or school counsellor if any of the following situations prevent you from writing a diploma exam you registered for:. You may be permitted to write at a Special Writing Centre if you are out of the province when diploma exams are administered. Speak with your principal for more information. You may rewrite a diploma exam or ask to have it rescored if you believe that your diploma exam mark does not accurately reflect your level of achievement in a course.

To request a rescore of a diploma exam, apply online using myPass. The deadline to request a rescore is provided on your Results Statement. Requests received after the deadline will not be granted.

Your most recent school-awarded mark will be blended with the rescore exam mark, and a new Results Statement will be available on myPass. The mark resulting from rescoring becomes your final exam mark, even if it is lower than the original mark. Rescoring the machine-scored section rarely changes the score. Refer to the written response raw score reported on your Results Statement to help you decide if you want your exam rescored.

If a diploma exam has 2 parts, you must write or rewrite both parts of the diploma exam during the same diploma exam administration to earn credit for that diploma exam course. If this is impossible, talk to your principal or school counsellor.

When you repeat a course or rewrite a diploma exam, your new Results Statement will list your most recently earned marks. Your new transcript, if you request one, will show only the highest diploma exam mark and highest school-awarded mark earned.

Students are charged a non-refundable rewrite registration fee for a diploma exam if they have written a diploma exam in this course within the current or two previous school years.

Diploma exams will be offered for every diploma exam course in November, January, April, June and August administrations. Corn stalks and straw are similarly slow to break down because they are made up of a resistant form of cellulose. Particle size also is a relevant consideration; although the same amount of carbon is contained in comparable masses of wood chips and sawdust, the larger surface area in the sawdust makes its carbon more readily available for microbial use.

Another essential ingredient for successful composting is oxygen. As microorganisms oxidize carbon for energy, oxygen is used up and carbon dioxide is produced.

Without sufficient oxygen, the process will become anaerobic and produce undesirable odors, including the rotten-egg smell of hydrogen sulfide gas. So, how much oxygen is sufficient to maintain aerobic conditions? Some compost systems are able to maintain adequate oxygen passively, through natural diffusion and convection. Other systems require active aeration, provided by blowers or through turning or mixing the compost ingredients. Adequate phosphorus, potassium, and trace minerals calcium, iron, boron, copper, etc.

Normally these nutrients are not limiting because they are present in ample concentration in the compost source materials. A pH between 5. As bacteria and fungi digest organic matter, they release organic acids. In the early stages of composting, these acids often accumulate. The resulting drop in pH encourages the growth of fungi and the breakdown of lignin and cellulose. Usually the organic acids become further broken down during the composting process. If the system becomes anaerobic, however, acid accumulation can lower the pH to 4.

In such cases, aeration usually is sufficient to return the compost pH to acceptable ranges.
