My son has a big problem with the study of biology and mathematics.
Perhaps you use the services of a tutor and could you suggest a good one?

Now I'm in my 4th year and I understand you very much, it took me a long time to find a good biology tutor, which was not as easy as I thought it would be.
But a good friend of mine was also looking for a biology tutor, which was good for me.
The same site Up Skills Tutor had tutors not only for math but also for different languages and exact sciences, which helped me a lot.
There are teachers there for both young preschoolers and adults.
They have a very good and up-to-date curriculum which I liked the most about it, they were great at finding an approach to everyone.
So I can say that I personally found a good tutor through my friend.

It took me so long to find a good French tutor too, but then my mom's friend told me.

Exams are not as scary for me as an interview at my medical school. Yes, I will be going to medical school soon and I have an ANZ interview. For a long time I was worried about this, because there is very little information on the Internet and it is not clear what questions can expect me and how tricky they can be. But I was still lucky to stumble upon the site https://www.medicmind.co.uk/interview-online-course/ where I was able to hire an excellent tutor for myself, who was able to quickly prepare me for the upcoming interview and explained in detail what questions await me .
