Answers of these Biology Questions

Disadvantages in higher education, sadly, also exist.

Minus one.

Cost of education. As mentioned above, the general standard of living in the country is declining, and the cost of training is increasing. Not every parent will be able to pay for the child’s education for 5-6 years. Now it’s not uncommon when parents spend more than 70-80% of their monthly income to pay for their child’s education. And if there are two or three children? It is easy to calculate that if you take the total amount spent on studying at a middle-level university, you can start a small business of your own, do business, buy a house or an apartment. And, having his own store or workshop, a particularly practical person will begin to doubt the feasibility of spending money on training with a rather illusive prospect of getting a job.

Minus the second.

Unfortunately, the quality of higher education has declined significantly in recent years. If before the Soviet educational system was considered one of the best in the world, now many “commercial” universities are being created, the purpose of which is only business. The teaching staff in such institutions is not professional, the material base is weak, and there are no social and educational programs. As a result, the student spends 5 years on education, which will absolutely not help him in finding a job. Now in large publications on employment, one can often find advertisements of the type: “A specialist is required . From the university “XXX” – do not disturb. “
