Dear Jordan,
Thanks your letter. It was great to hear you. Sorry I haven't written sooner but I've been really busy with exams.

In your letter you asked me about language school would be better for you. I’ll give you some tips about it with pleasure.

Firstly, about your lesson schedule, I suggest you don’t study the very intensive 2 week (60 hour) course it's too stressful and those courses don't have a high success rate. It's much sensible to do the 4 week (60 hour) course. , on the 4 week course there will be much more time to involved in some serious speaking practice.

, accommodation, living with a local family is better staying in a hostel because you’ll have a great chance to improve your everyday spoken English. Thirdly about excursions. If I you, instead of paying high prices for them, I’d buy a map of the city and go round all the places of interest on foot or by bike, which you can rent there.

Finally, my last piece of advice is, as you like clubbing and partying so much you should choose the school which is in London where there's lots of nightlife. I think the out of town school would be a bit boring for you.

Drop a line soon and me know what you decide to do.

Best wishes,
