I used to find general ledgers confusing without an analysing chart. But I just practised and practised and practised and now I find them really easy and not too difficult at all. It's sort of hard to explain how to do it in a reply like this but maybe just ask your teacher to go through it with you because they're really not that hard once you get the hang of it. You just have to basically make sure that both sides of the ledgers total to be the same and you have to put the transactions in that affect.
A good way to remember it is the acronym ↓O↑A↓L↑E↓R↑. Owners Equity, Asset, Liability, Expense, Revenue.
For example, On January 1, if a business purchased $7000 stock plus GST, Stock Control (asset) would increase by 7000 as that amount of stock was purchased, GST clearing (Liability) would decrease 700 (As the business no longer owes that money to the ATO but the business they purchased from now do) and Bank (Asset) will decrease by 7700 as the business now just spent $7700 of their bank money on the stock.
I'll attach a word document to try and explain it a bit better from here.
I hope I sort of help
