Once you have done all your exam preparation, it is imperative to make sure that you curb your stress levels as much as possible on the day that you have to write. The calmer you are, the better the outcome!

Final exam season has arrived at the University of the Free State (UFS), and we would like to share a few quick and easy tips you can follow to ensure that you make it through successfully!
Here’s how you can beat exams: 

Step 1: Make sure that you prepare well beforehand to give yourself enough time to study. Prepare a study schedule that fits your way of studying, and do not leave anything for the last minute. It is probably easier to thrive on last-minute studying, but often this way of partial study is not the best approach for exam prep. Prioritise your studying based on how many exams you have, how many pages you have to learn, and the days you have left to study. 

Step 2: Study and practise your work using previous exam papers. This will help you see and understand the format and formulation of possible questions, and can aid you in knowing what to expect, and help you practise and estimate how much time you should spend on answering each question.

Step 3: Eat healthy and use your study/friend groups as a stimulant. Make sure to stock up and energise yourself with a lot of water and nutritional study snacks to extend your concentration and commitment to studying. Avoid overeating and consuming rich, fatty foods that will make you feel tired and sleepy. Likewise, studying in groups can also help you get the answers you need and finish tasks faster. You may have questions that your friends have the answers to, as long as you effectively plan how much time you spend deliberating on a question.

Last but not least, make sure that you give yourself regulated study breaks between various chapters or topics, and let your brain take it all in!

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
