Hi [Имя друга],
Thank you for your email. It’s great to hear from you!
I completely understand your stress about the upcoming exams. They can indeed be quite challenging, but with a good plan, you’ll be able to handle them just fine.
As for preparing for the tests, it’s generally recommended to study for about 90-110 hours in total, depending on your familiarity with the subjects and your learning style. You might want to break this down into daily study sessions to make it more manageable.
It's also important to balance study with breaks to maintain focus. Perhaps consider pinpointing the topics you find most challenging and allocate more time to them. Besides, using old exams for practice can be incredibly helpful.
Lastly, make sure to get enough rest and eat well. Your brain will work much better if you’re on top form physically.
Let me know if you need any more tips or if you just want to discuss specific subjects. We’re in this together!
Best wishes,
[Твоё имя]
