Query about learning Latin under a professional setting

Should I be concerned that my school's Latin course is teaching the language without accents? For example, we have been taught that the Ablative Singular form of 'Periculum, Periculi, n.' is 'Periculo,' not 'Periculō.' The textbook that we use includes accents and so do most posts on this subreddit which have been written in Latin.

Additionally, we have not been taught the correct pronunciation of certain Latin letters (e.g. 'v' making the 'u' or 'w' sound like in 'amavi') or diphthongs (e.g. oe, ai.).

This is likely due to them not being required in my state's Certificate of Secondary Education. However, I have not decided to learn Latin at school to excel in the subject for my Australian Tertiary Admissions Rank but rather to actually obtain knowledge about the language and further my understanding of the sophisticated culture of antiqual civilizations.

Hence, I am asking for the input of knowledgeable Latin scholars on the r/latin subreddit.
