Make your months pay
But when it comes to your finances, you've still got a chance to make a clean sweep.
With April being the start of the financial year, now is the time you need to make your money resolutions - and stick to them.
So here, with the help of Moneyfacts, the financial experts, is your cut-out-and-keep financial calendar. Pop it on your fridge door, or even on the staffroom noticeboard, and check it every month. Make sure you include dates that are specific to you, like when a 0 per cent credit card deal runs out, when a hire purchase agreement ends or when the direct debit payments from your bank account stop. Simple steps, but they could save you a lot
Start the financial year with a clean sweep - file statements and essential documents and shred what is no longer needed. If you are running a business as well as teaching, keep statements for six years. Otherwise, you just need to keep them for two.
If you haven't already started, put money aside for your summer break.
Estimate how much you will need and how much you need to save between now and going away. Check out www.moneyfacts.co.uk to see which savings account gives the best interest.
Peak season for home buying so make sure you are on the best mortgage deal.
Check when your current arrangement ends. If you are on a standard variable rate, you could be paying far more than you need. Look for the best fixed rate deals on www.moneyfacts.co.uk or www.fool.co.uk.
Set up direct debits to pay your bills while you're away on holiday to avoid late payment penalties. Check you've got adequate buildings and contents insurance to cover your home while you're away. Have you bought expensive jewellery or furniture since you last reviewed it? See also www.moneysupermarket.com to make sure you're not paying over the odds.
Signing up online could save you more.

Christmas is getting closer. How are those savings accounts doing? Check what you've got and plan your shopping list before you hit the shops. It can be easier to budget if you shop online - just make sure you keep a careful record of your purchases.
So, OK, we all get carried away. But if you must spend, at least get a 0 per cent credit card and work out exactly what you can afford to spend on the card - and pay off within the 0 per cent period.
Batten down the hatches and work out exactly what your monthly outgoings are - including any credit card debt and one-off payments such as servicing the boiler or burglar alarm. Work out what you've got left and start saving again. If you are a self-assessment taxpayer, make sure you file before January 31 or you face a pound;100 fine. See www.hmrc.co.uk to register and file online.
Thinking of buying a new car? Buy now, just before the registration plate change in March, and you could get yourself a great deal. Don't opt for forecourt finance unless it's 0 per cent.
