The second day of Enem (National Baccalaureate Exam) ended today with two traditional tests in the evaluation of teachers of courses attended by the report of the Twitter.
There were 45 questions of natural sciences (biology, physics and chemistry) and 45 questions of mathematics, made in five hours of examination.
“They were topics that are part of the Enem tradition, contextualized and that dialogue well with the daily lives of the students,” says Daniel Perry, director of the Anglo Course.
A math question, for example, addresses an anagram (when rearranging the letters of one or more words to form another word or phrase) from the “Harry Potter” series of books and movies.
The test did not address the new coronavirus, as the interviewed teachers expected, it was not controversial and was, in general, of medium level, according to the teachers.
It was a test that followed the trend towards neutrality and loaded the students with rice and beans.

The Enem held this month is the 2020 deferred exam, due to the covid-19 pandemic. There were about 5.5 million subscribers.
On the first day, however, the exam registered a record abstention, with 51.5% of registered candidates absent.
The abstentions of the second and general session will be announced in an interview by Inep (National Institute for Educational Studies and Research Anísio Teixeira), at 8:00 p.m.
natural Sciences
The natural science exam was considered well balanced between the three disciplines that make up the area – biology, chemistry and physics – according to the teachers of the courses.
Also, all three tests brought up classic Enem themes.
Biology, for example, was very ecologically charged and had three questions about the impact of oil exploration. There were also questions about blood type, genetics, and population dynamics.
It was a demanding test. “It was a medium to difficult test. The student needed a good interpretation of the text and graphics,” says Guilherme Francisco, a biology professor at Target.
“We had doubts about biotechnology, a common theme at Enem. But this edition demanded to know the mechanisms and techniques of this biotechnology, in addition to the ethical aspects of it ”, says Ricardo Jorge, professor of biology at the Farias Brito System.
Despite the perception that it was a traditional test, the lack of some issues was striking. “Human physiology, which followed ecology as the most popular subjects, did not appear this year”, says Jorge.
The chemistry test was quite diverse and smooth, according to Sérgio Teixeira, a chemistry professor at Target.
“Without laborious questions and knowing the subject, the student would not waste much time, he would practically have a direct and immediate answer,” he says.
Contents and concepts of the entire high school appeared, from physical chemistry to organic chemistry, in subjects such as mixtures, stoichiometry and radioactivity.
The physics test, also considered traditional, brought up classic themes: uniform movement, horizontal launch, electrostatic, among others.
“It was a refined test with everyday topics, such as a question about city traffic that talked about calculating the time interval between traffic lights and another about the concept of energy production in a hydroelectric plant,” says Thomas Haupt, professor of Target physics.
Mathematics
In addition to the question that brought up an anagram from the Harry Potter series, the math test was also considered traditional.
“Following this trend, more than 50% of the questions could be solved with simple concepts of ratios and proportions,” says Fernando da Espiritu Santo, from Polyhedron.
Enem’s largest test, with 45 questions, brought content such as probability, scientific notation, rule of three, combinatorial analysis, and percentage.
“It was a very well prepared test, but not very easy,” says Marcelo Melo, a math teacher at Target. He points out, for example, that an exponential topic was very laborious. “It was necessary to work element by element.”
He was struck by the absence of questions of analytical geometry and trigonometric functions.
